NAME
       xterm - terminal emulator for X

SYNOPSIS
       xterm [-toolkitoption ...] [-option ...] [shell]

DESCRIPTION
       The  xterm  program is a terminal emulator for the X Window System.  It
       provides DEC VT102/VT220 (VTxxx) and Tektronix 4014  compatible  termi-
       nals  for  programs that cannot use the window system directly.  If the
       underlying operating system  supports  terminal  resizing  capabilities
       (for  example,  the  SIGWINCH  signal  in systems derived from 4.3bsd),
       xterm will use the facilities to notify programs running in the  window
       whenever it is resized.

       The  VTxxx  and  Tektronix 4014 terminals each have their own window so
       that you can edit text in one and look at graphics in the other at  the
       same  time.   To maintain the correct aspect ratio (height/width), Tek-
       tronix graphics will be restricted to the largest  box  with  a  4014's
       aspect  ratio  that will fit in the window.  This box is located in the
       upper left area of the window.

       Although both windows may be displayed at the same time, one of them is
       considered  the ''active'' window for receiving keyboard input and ter-
       minal output.  This is the window that contains the text  cursor.   The
       active  window  can  be  chosen  through  escape  sequences,  the  ''VT
       Options'' menu in the VTxxx window, and the ''Tek Options'' menu in the
       4014 window.

EMULATIONS
       The  VT102  emulation  is fairly complete, but does not support autore-
       peat.  Double-size characters  are  displayed  properly  if  your  font
       server  supports  scalable fonts.  The VT220 emulation does not support
       soft fonts, it is otherwise complete.   Termcap(5)  entries  that  work
       with  xterm  include  an  optional  platform-specific entry, ''xterm,''
       ''vt102,'' ''vt100'' and ''ansi,'' and ''dumb.''   xterm  automatically
       searches the termcap file in this order for these entries and then sets
       the ''TERM'' and the ''TERMCAP'' environment variables.  You  may  also
       use  ''vt220,''   but  must  set  the terminal emulation level with the
       decTerminalID resource.  (The ''TERMCAP'' environment variable  is  not
       set  if xterm is linked against a terminfo library, since the requisite
       information is not  provided  by  the  termcap  emulation  of  terminfo
       libraries).

       Many  of  the special xterm features may be modified under program con-
       trol through a set of escape  sequences  different  from  the  standard
       VT102 escape sequences.  (See the Xterm Control Sequences document.)

       The  Tektronix  4014 emulation is also fairly good.  It supports 12-bit
       graphics addressing, scaled to the window size.   Four  different  font
       sizes and five different lines types are supported.  There is no write-
       through or defocused mode support.  The  Tektronix  text  and  graphics
       commands  are recorded internally by xterm and may be written to a file
       by sending the COPY escape sequence (or through the Tektronix menu; see
       below).   The  name  of  the  file will be ''COPYyyyy-MM-dd.hh:mm:ss'',
       where yyyy, MM, dd, hh, mm and ss  are  the  year,  month,  day,  hour,
       minute  and  second when the COPY was performed (the file is created in
       the directory xterm is started in, or the home directory  for  a  login
       xterm).

       Not all of the features described in this manual are necessarily avail-
       able in this version of xterm.  Some (e.g., the  non-VT220  extensions)
       are  available only if they were compiled in, though the most commonly-
       used are in the default configuration.

OTHER FEATURES
       Xterm automatically highlights the text cursor when the pointer  enters
       the  window  (selected) and unhighlights it when the pointer leaves the
       window (unselected).  If the window is the focus window, then the  text
       cursor is highlighted no matter where the pointer is.

       In VT102 mode, there are escape sequences to activate and deactivate an
       alternate screen buffer, which is the same size as the display area  of
       the  window.   When activated, the current screen is saved and replaced
       with the alternate screen.  Saving of lines scrolled off the top of the
       window is disabled until the normal screen is restored.  The termcap(5)
       entry for xterm allows the visual editor vi(1) to switch to the  alter-
       nate  screen  for  editing  and to restore the screen on exit.  A popup
       menu entry makes it simple to switch between the normal  and  alternate
       screens for cut and paste.

       In either VT102 or Tektronix mode, there are escape sequences to change
       the name of the windows.  Additionally, in VT102 mode, xterm implements
       the window-manipulation control sequences from dtterm, such as resizing
       the window, setting its location on the screen.

       Xterm allows character-based applications to receive mouse events (cur-
       rently  button-press  and  release events, and button-motion events) as
       keyboard control sequences.  See Xterm Control Sequences for details.

OPTIONS
       The xterm terminal emulator accepts the standard X Toolkit command line
       options  as  well  as many application-specific options.  If the option
       begins with a '+' instead of a '-',  the  option  is  restored  to  its
       default  value.  The -version and -help options are interpreted even if
       xterm cannot open the display, and are useful for testing and  configu-
       ration scripts:

       -version
               This  causes  xterm  to  print a version number to the standard
               output.

       -help   This causes xterm to print out a verbose message describing its
               options,  one per line.  The message is written to the standard
               output.  Xterm generates this message, sorting  it  and  noting
               whether a "-option" or a "+option" turns the feature on or off,
               since some features historically have been one  or  the  other.
               Xterm  generates  a  concise help message (multiple options per
               line) when an unknown option is used, e.g.,
                    xterm -z

               If the logic for a particular option such  as  logging  is  not
               compiled  into xterm, the help text for that option also is not
               displayed by the -help option.

       One parameter (after all options) may be given.  That overrides xterm's
       built-in  choice  of  shell  program.   Normally xterm checks the SHELL
       variable.  If that is not set, xterm tries to  use  the  shell  program
       specified  in  the  password  file.   If  that  is  not set, xterm uses
       /bin/sh.  If the parameter names an executable file,  xterm  uses  that
       instead.   The parameter must be an absolute path, or name a file found
       on the user's PATH (and thereby construct an absolute  path).   The  -e
       option  cannot be used with this parameter since it uses all parameters
       following the option.

       The other options are used to control the appearance and behavior.  Not
       all options are necessarily configured into your copy of xterm:

       -132    Normally,  the  VT102  DECCOLM  escape  sequence  that switches
               between 80 and 132 column mode is ignored.  This option  causes
               the  DECCOLM  escape  sequence  to be recognized, and the xterm
               window will resize appropriately.

       -ah     This option indicates that xterm should  always  highlight  the
               text cursor.  By default, xterm will display a hollow text cur-
               sor whenever the focus is lost or the pointer leaves  the  win-
               dow.

       +ah     This  option  indicates  that xterm should do text cursor high-
               lighting based on focus.

       -ai     This option disables active icon support if  that  feature  was
               compiled  into  xterm.  This is equivalent to setting the vt100
               resource activeIcon to ''false''.

       +ai     This option enables active icon support  if  that  feature  was
               compiled  into  xterm.  This is equivalent to setting the vt100
               resource activeIcon to ''true''.

       -aw     This option indicates that auto-wraparound should  be  allowed.
               This  allows  the cursor to automatically wrap to the beginning
               of the next line when when it is at the rightmost position of a
               line and text is output.

       +aw     This  option  indicates  that  auto-wraparound  should  not  be
               allowed.

       -b number
               This option specifies the size of the inner  border  (the  dis-
               tance  between  the outer edge of the characters and the window
               border) in pixels.  That is the vt100 internalBorder  resource.
               The default is 2.

       +bc     turn  off text cursor blinking.  This overrides the cursorBlink
               resource.

       -bc     turn on text cursor blinking.  This overrides  the  cursorBlink
               resource.

       -bcf milliseconds
               set the amount of time text cursor is off when blinking via the
               cursorOffTime resource.

       -bcn milliseconds
               set the amount of time text cursor is on when blinking via  the
               cursorOffTime resource.

       -bdc    Set  the vt100 resource colorBDMode to ''false'', disabling the
               display of characters with bold attribute as color

       +bdc    Set the vt100 resource colorBDMode to  ''true'',  enabling  the
               display  of characters with bold attribute as color rather than
               bold

       -cb     Set the vt100 resource cutToBeginningOfLine to ''false''.

       +cb     Set the vt100 resource cutToBeginningOfLine to ''true''.

       -cc characterclassrange:value[,...]
               This sets classes indicated by the given ranges  for  using  in
               selecting  by  words.   See  the  section  specifying character
               classes.  and discussion of the charClass resource.

       -cjk_width
               Set the cjkWidth resource to ''true''.  When turned on, charac-
               ters  with  East  Asian Ambiguous (A) category in UTR 11 have a
               column width of 2.  Otherwise, they have a column width  of  1.
               This may be useful for some legacy CJK text terminal-based pro-
               grams assuming box drawings and others to have a  column  width
               of  2.  It also has to be turned on when you specify a TrueType
               CJK double-width (bi-width/monospace) font either with  -fa  at
               the   command  line  or  faceName  resource.   The  default  is
               ''false''

       +cjk_width
               Reset the cjkWidth resource.

       -class string
               This option allows you  to  override  xterm's  resource  class.
               Normally  it is ''XTerm'', but can be set to another class such
               as ''UXTerm'' to override selected resources.

       -cm     This option disables recognition of  ANSI  color-change  escape
               sequences.  It sets the colorMode resource to ''false''.

       +cm     This  option  enables  recognition  of ANSI color-change escape
               sequences.  This is the same as the vt100 resource colorMode.

       -cn     This option indicates that newlines should not be cut in  line-
               mode selections.  It sets the cutNewline resource to ''false''.

       +cn     This option indicates that newlines should be cut in  line-mode
               selections.  It sets the cutNewline resource to ''true''.

       -cr color
               This  option  specifies  the color to use for text cursor.  The
               default is to use the same foreground color that  is  used  for
               text.  It sets the cursorColor resource according to the param-
               eter.

       -cu     This option indicates that xterm should work around  a  bug  in
               the more(1) program that causes it to incorrectly display lines
               that are exactly the width of the window and are followed by  a
               line beginning with a tab (the leading tabs are not displayed).
               This option is so named because it was originally thought to be
               a bug in the curses(3x) cursor motion package.

       +cu     This  option  indicates  that  xterm should not work around the
               more(1) bug mentioned above.

       -dc     This option disables the escape sequence to change dynamic col-
               ors:  the vt100 foreground and background colors, its text cur-
               sor color, the pointer cursor foreground and background colors,
               the  Tektronix  emulator  foreground and background colors, its
               text cursor color and highlight color.   The  option  sets  the
               dynamicColors option to ''false''.

       +dc     This  option enables the escape sequence to change dynamic col-
               ors.  The option sets the dynamicColors option to ''true''.

       -e program [ arguments ... ]
               This option specifies the program (and its command  line  argu-
               ments)  to be run in the xterm window.  It also sets the window
               title and icon name to be the basename  of  the  program  being
               executed  if  neither  -T nor -n are given on the command line.
               This must be the last option on the command line.

       -en encoding
               This option determines the encoding on which  xterm  runs.   It
               sets  the locale resource.  Encodings other than UTF-8 are sup-
               ported by using luit.  The -lc option should be used instead of
               -en for systems with locale support.

       -fb font
               This  option  specifies  a font to be used when displaying bold
               text.  This font must be the  same  height  and  width  as  the
               normal font.  If only one of the normal or bold fonts is speci-
               fied, it will be used as the normal font and the bold font will
               be  produced  by  overstriking this font.  The default is to do
               overstriking of the normal font.  See also  the  discussion  of
               boldFont and boldMode resources.

       -fa pattern
               This  option  sets  the  pattern  for  fonts  selected from the
               FreeType library if support for that library was compiled  into
               xterm.   This corresponds to the faceName resource.  When a CJK
               double-width font is specified, you also need to  turn  on  the
               cjkWidth resource.

       -fbb    This option indicates that xterm should compare normal and bold
               fonts bounding boxes to ensure they are  compatible.   It  sets
               the freeBoldBox resource to ''false''.

       +fbb    This  option indicates that xterm should not compare normal and
               bold fonts bounding boxes to ensure they  are  compatible.   It
               sets the freeBoldBox resource to ''true''.

       -fbx    This  option  indicates  that  xterm should not assume that the
               normal and bold fonts have VT100 line-drawing  characters.   If
               any  are  missing, xterm will draw the characters directly.  It
               sets the forceBoxChars resource to ''false''.

       +fbx    This option indicates that xterm should assume that the  normal
               and bold fonts have VT100 line-drawing characters.  It sets the
               forceBoxChars resource to ''true''.

       -fd pattern
               This option sets the pattern for  double-width  fonts  selected
               from  the FreeType library if support for that library was com-
               piled into xterm.  This corresponds to  the  faceNameDoublesize
               resource.

       -fi font
               This  option sets the font for active icons if that feature was
               compiled into xterm.  See also the discussion of  the  iconFont
               resource.

       -fs size
               This  option  sets  the  pointsize  for fonts selected from the
               FreeType library if support for that library was compiled  into
               xterm.  This corresponds to the faceSize resource.

       -fw font
               This  option  specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as  wide
               as  the font that will be used to draw normal text.  If no dou-
               blewidth font is found, it will improvise,  by  stretching  the
               normal font.  This corresponds to the wideFont resource.

       -fwb font
               This  option  specifies the font to be used for displaying bold
               wide text.  By default, it will attempt to use a font twice  as
               wide  as  the  font that will be used to draw bold text.  If no
               doublewidth font is found, it will improvise, by stretching the
               bold font.  This corresponds to the wideBoldFont resource.

       -fx font
               This  option  specifies  the font to be used for displaying the
               preedit string in the "OverTheSpot" input method.  See also the
               discussion of the ximFont resource.

       -hc color
               This  option  specifies  the color to use for the background of
               selected or otherwise  highlighted  text.   If  not  specified,
               reverse  video  is  used.  See the discussion of the highlight-
               Color resource.

       -hf     This option indicates that HP Function Key escape codes  should
               be  generated  for  function  keys.  It sets the hpFunctionKeys
               resource to ''true''.

       +hf     This option indicates that HP Function Key escape codes  should
               not be generated for function keys.  It sets the hpFunctionKeys
               resource to ''false''.

       -hold   Turn on the hold resource, i.e.,  xterm  will  not  immediately
               destroy  its  window when the shell command completes.  It will
               wait until you use the window manager to destroy/kill the  win-
               dow,  or  if you use the menu entries that send a signal, e.g.,
               HUP or KILL.

       +hold   Turn off  the  hold  resource,  i.e.,  xterm  will  immediately
               destroy its window when the shell command completes.

       -ie     Turn on the ptyInitialErase resource, i.e., use the pseudo-ter-
               minal's sense of the stty erase value.

       +ie     Turn off the ptyInitialErase resource, i.e., set the stty erase
               value  using  the  kb string from the termcap entry as a refer-
               ence, if available.

       -im     Turn on the useInsertMode resource, which forces use of  insert
               mode  by  adding appropriate entries to the TERMCAP environment
               variable.

       +im     Turn off the useInsertMode resource.

       -into windowId
               Given an X window identifier (a decimal  integer),  xterm  will
               reparent  its  top-level  shell widget to that window.  This is
               used to embed xterm within other applications.

       -j      This option indicates that xterm should do jump scrolling.   It
               corresponds  to  the  jumpScroll  resource.   Normally, text is
               scrolled one line at a time; this option allows xterm  to  move
               multiple  lines  at  a  time  so  that  it does not fall as far
               behind.  Its use is strongly recommended since it  makes  xterm
               much  faster  when scanning through large amounts of text.  The
               VT100 escape sequences for enabling and disabling smooth scroll
               as  well  as  the  ''VT Options'' menu can be used to turn this
               feature on or off.

       +j      This option indicates that xterm should not do jump  scrolling.

       -k8     This   option   sets   the   allowC1Printable  resource.   When
               allowC1Printable is set, xterm overrides the mapping of C1 con-
               trol characters (code 128-159) to treat them as printable.

       +k8     This option resets the allowC1Printable resource.

       -kt keyboardtype
               This  option  sets  the keyboardType resource.  Possible values
               include: ''unknown'', ''default'', ''hp'', ''sco'', ''sun'' and
               ''vt220''.

               The  value ''unknown'', causes the corresponding resource to be
               ignored.

               The value  ''default'',  suppresses  the  associated  resources
               hpFunctionKeys,  scoFunctionKeys,  sunFunctionKeys  and sunKey-
               board, using the Sun/PC keyboard layout.

       -l      Turn logging on.  Normally logging is  not  supported,  due  to
               security  concerns.   Some  versions  of xterm may have logging
               enabled.  The logfile is written to the  directory  from  which
               xterm is invoked.  The filename is generated, of the form

                    XtermLog.XXXXXX

               or

                    Xterm.log.hostname.yyyy.mm.dd.hh.mm.ss.XXXXXX

               depending on how xterm was built.

       +l      Turn logging off.

       -lc     Turn  on  support  of various encodings according to the users'
               locale setting, i.e., LC_ALL,  LC_CTYPE,  or  LANG  environment
               variables.   This  is  achieved by turning on UTF-8 mode and by
               invoking luit  for  conversion  between  locale  encodings  and
               UTF-8.   (luit  is  not invoked in UTF-8 locales.)  This corre-
               sponds to the locale resource.

               The actual list of encodings which are supported is  determined
               by  luit.   Consult  the  luit manual page for further details.
               See also the discussion of the -u8 option which supports  UTF-8
               locales.

       +lc     Turn  off  support  of automatic selection of locale encodings.
               Conventional 8bit mode or, in UTF-8 locales or with -u8 option,
               UTF-8 mode will be used.

       -lcc path
               File  name  for the encoding converter from/to locale encodings
               and UTF-8 which is used with -lc  option  or  locale  resource.
               This corresponds to the localeFilter resource.

       -leftbar
               Force  scrollbar to the left side of VT100 screen.  This is the
               default, unless you have set the rightScrollBar resource.

       -lf filename
               Specify the log-filename.  See the -l option.

       -ls     This option indicates that the shell that  is  started  in  the
               xterm  window  will be a login shell (i.e., the first character
               of argv[0] will be a dash, indicating  to  the  shell  that  it
               should read the user's .login or .profile).

               The  -ls  flag and the loginShell resource are ignored if -e is
               also given, because xterm does not know how to make  the  shell
               start  the  given  command  after whatever it does when it is a
               login shell - the user's shell of choice need not be  a  Bourne
               shell  after all.  Also, xterm -e is supposed to provide a con-
               sistent functionality for other applications that need to start
               text-mode  programs  in  a  window,  and if loginShell were not
               ignored, the result of ~/.profile might interfere with that.

               If you do want the effect of -ls and -e simultaneously, you may
               get away with something like
                      xterm -e /bin/bash -l -c "my command here"

               Finally,  -ls  is  not completely ignored, because xterm -ls -e
               does write a /etc/wtmp entry (if configured to do so),  whereas
               xterm -e does not.

       +ls     This option indicates that the shell that is started should not
               be a login shell (i.e., it will be a normal ''subshell'').

       -mb     This option indicates that xterm should ring a margin bell when
               the  user  types near the right end of a line.  This option can
               be turned on and off from the ''VT Options'' menu.

       +mb     This option indicates that margin bell should not be rung.

       -mc milliseconds
               This option specifies  the  maximum  time  between  multi-click
               selections.

       -mesg   Turn  off the messages resource, i.e., disallow write access to
               the terminal.

       +mesg   Turn on the messages resource, i.e., allow write access to  the
               terminal.

       -mk_width
               Set  the  mkWidth resource to ''true''.  This makes xterm use a
               built-in version of the wide-character width calculation.   The
               default is ''false''

       +mk_width
               Reset the mkWidth resource.

       -ms color
               This option specifies the color to be used for the pointer cur-
               sor.  The default is to use the foreground  color.   This  sets
               the pointerColor resource.

       -nb number
               This  option  specifies the number of characters from the right
               end of a line at which the margin bell, if enabled, will  ring.
               The default is 10.

       -nul    This option disables the display of underlining.

       +nul    This option enables the display of underlining.

       -pc     This  option enables the PC-style use of bold colors (see bold-
               Colors resource).

       +pc     This option disables the PC-style use of bold colors.

       -pob    This option indicates that the window should be raised whenever
               a Control-G is received.

       +pob    This  option  indicates  that  the  window should not be raised
               whenever a Control-G is received.

       -rightbar
               Force scrollbar to the right side of VT100 screen.

       -rvc    This option disables the display  of  characters  with  reverse
               attribute as color.

       +rvc    This  option  enables  the  display  of characters with reverse
               attribute as color.

       -rw     This  option  indicates  that  reverse-wraparound   should   be
               allowed.   This  allows the cursor to back up from the leftmost
               column of one line to the  rightmost  column  of  the  previous
               line.  This is very useful for editing long shell command lines
               and is encouraged.  This option can be turned on and  off  from
               the ''VT Options'' menu.

       +rw     This  option  indicates  that  reverse-wraparound should not be
               allowed.

       -s      This option indicates that  xterm  may  scroll  asynchronously,
               meaning  that the screen does not have to be kept completely up
               to date while scrolling.  This allows xterm to run faster  when
               network  latencies  are  very high and is typically useful when
               running across a very large internet or many gateways.

       +s      This option indicates that xterm should scroll synchronously.

       -samename
               Does not send title and icon  name  change  requests  when  the
               request  would  have  no effect: the name is not changed.  This
               has the advantage of preventing flicker and the disadvantage of
               requiring  an  extra  round  trip to the server to find out the
               previous value.  In practice this should never be a problem.

       +samename
               Always send title and icon name change requests.

       -sb     This option indicates  that  some  number  of  lines  that  are
               scrolled  off  the top of the window should be saved and that a
               scrollbar should be  displayed  so  that  those  lines  can  be
               viewed.   This  option  may  be turned on and off from the ''VT
               Options'' menu.

       +sb     This option indicates that a scrollbar should not be displayed.

       -sf     This option indicates that Sun Function Key escape codes should
               be generated for function keys.

       +sf     This option indicates that the standard escape codes should  be
               generated for function keys.

       -si     This  option indicates that output to a window should not auto-
               matically reposition the screen to the bottom of the  scrolling
               region.   This  option  can  be turned on and off from the ''VT
               Options'' menu.

       +si     This option indicates that output to a window should  cause  it
               to scroll to the bottom.

       -sk     This  option  indicates  that  pressing  a  key while using the
               scrollbar to review previous lines of  text  should  cause  the
               window  to be repositioned automatically in the normal position
               at the bottom of the scroll region.

       +sk     This option indicates that  pressing  a  key  while  using  the
               scrollbar should not cause the window to be repositioned.

       -sl number
               This  option  specifies  the  number of lines to save that have
               been scrolled off the top of the screen.  This  corresponds  to
               the saveLines resource.  The default is 64.

       -sm     This  option,  corresponding  to the sessionMgt resource, indi-
               cates that xterm should set up session manager callbacks.

       +sm     This option indicates that xterm should not set up session man-
               ager callbacks.

       -sp     This  option  indicates that Sun/PC keyboard should be assumed,
               providing mapping for keypad '+' to ',', and  CTRL-F1  to  F13,
               CTRL-F2 to F14, etc.

       +sp     This  option indicates that the standard escape codes should be
               generated for keypad and function keys.

       -t      This option indicates that  xterm  should  start  in  Tektronix
               mode,  rather  than  in  VT102 mode.  Switching between the two
               windows  is  done  using  the  ''Options''  menus.   Termcap(5)
               entries   that   work   with  xterm  ''tek4014,''  ''tek4015,''
               ''tek4012'', ''tek4013'' and ''tek4010,'' and ''dumb.''   xterm
               automatically searches the termcap file in this order for these
               entries and then sets the ''TERM'' and the ''TERMCAP'' environ-
               ment variables.

       +t      This option indicates that xterm should start in VT102 mode.

       -tb     This  option,  corresponding to the toolBar resource, indicates
               that xterm should display a toolbar (or menubar) at the top  of
               its window.  The buttons in the toolbar correspond to the popup
               menus, e.g., control/left/mouse for "Main Options".

       +tb     This option indicates that xterm should not set up a toolbar.

       -ti term_id
               Specify the name used by xterm to select the  correct  response
               to terminal ID queries.  It also specifies the emulation level,
               used to  determine  the  type  of  response  to  a  DA  control
               sequence.   Valid values include vt52, vt100, vt101, vt102, and
               vt220 (the "vt" is  optional).   The  default  is  vt100.   The
               term_id  argument  specifies  the terminal ID to use.  (This is
               the same as the decTerminalID resource).

       -tm string
               This option specifies a series  of  terminal  setting  keywords
               followed  by the characters that should be bound to those func-
               tions, similar to the stty program.   The  keywords  and  their
               values are described in detail in the ttyModes resource.

       -tn name
               This  option  specifies the name of the terminal type to be set
               in the  TERM  environment  variable.   It  corresponds  to  the
               termName resource.  This terminal type must exist in the termi-
               nal database (termcap or terminfo, depending on  how  xterm  is
               built)  and  should  have li# and co# entries.  If the terminal
               type is not found, xterm  uses  the  built-in  list  ''xterm'',
               ''vt102'', etc.

       -u8     This  option  sets  the utf8 resource.  When utf8 is set, xterm
               interprets incoming data as UTF-8.   This  sets  the  wideChars
               resource  as  a  side-effect,  but  the  UTF-8 mode set by this
               option prevents it from being turned off.  If you must turn  it
               on and off, use the wideChars resource.

               This option and the utf8 resource are overridden by the -lc and
               -en options and locale resource.  That is, if  xterm  has  been
               compiled  to  support  luit,  and  the  locale  resource is not
               ''false'' this option is ignored.  We recommend using  the  -lc
               option  or  the ''locale: true'' resource in UTF-8 locales when
               your operating system supports locale, or -en UTF-8  option  or
               the  ''locale: UTF-8'' resource when your operating system does
               not support locale.

       +u8     This option resets the utf8 resource.

       -ulc    This option disables the display of characters  with  underline
               attribute as color rather than with underlining.

       +ulc    This  option  enables  the display of characters with underline
               attribute as color rather than with underlining.

       -ut     This option indicates that xterm should not write a record into
               the the system utmp log file.

       +ut     This option indicates that xterm should write a record into the
               system utmp log file.

       -vb     This option indicates that a visual bell is preferred  over  an
               audible  one.   Instead of ringing the terminal bell whenever a
               Control-G is received, the window will be flashed.

       +vb     This option indicates that a visual bell should not be used.

       -wc     This option sets the wideChars  resource.   When  wideChars  is
               set, xterm maintains internal structures for 16-bit characters.
               If you do not set this resource to ''true'', xterm will  ignore
               the  escape  sequence  which  turns UTF-8 mode on and off.  The
               default is ''false''.

       +wc     This option resets the wideChars resource.

       -wf     This option indicates that xterm should wait for the window  to
               be mapped the first time before starting the subprocess so that
               the initial terminal size settings  and  environment  variables
               are  correct.   It is the application's responsibility to catch
               subsequent terminal size changes.

       +wf     This option indicates that xterm should not wait before  start-
               ing the subprocess.

       -ziconbeep percent
               Same  as  zIconBeep  resource.   If percent is non-zero, xterms
               that produce output while iconified will cause an  XBell  sound
               at  the  given  volume  and  have "***" prepended to their icon
               titles.  Most window managers will detect this  change  immedi-
               ately,  showing  you  which  window has the output.  (A similar
               feature was in x10 xterm.)

       -C      This option indicates that this window should  receive  console
               output.   This is not supported on all systems.  To obtain con-
               sole output, you must be the owner of the console  device,  and
               you  must  have  read  and write permission for it.  If you are
               running X under xdm on the console screen you may need to  have
               the  session  startup  and reset programs explicitly change the
               ownership of the console device in order to get this option  to
               work.

       -Sccn   This  option  allows  xterm  to  be used as an input and output
               channel for an existing program and is sometimes used  in  spe-
               cialized applications.  The option value specifies the last few
               letters of the name of a pseudo-terminal to use in slave  mode,
               plus  the  number  of  the  inherited  file descriptor.  If the
               option contains a ''/'' character, that delimits the characters
               used  for  the  pseudo-terminal  name from the file descriptor.
               Otherwise, exactly two characters are used from the option  for
               the pseudo-terminal name, the remainder is the file descriptor.
               Examples:
                      -S123/45
                      -Sab34

               Note that xterm does not close any file descriptor which it did
               not  open for its own use.  It is possible (though probably not
               portable) to have an application  which  passes  an  open  file
               descriptor  down  to  xterm  past  the initialization or the -S
               option to a process running in the xterm.

       The following command line arguments  are  provided  for  compatibility
       with  older versions.  They may not be supported in the next release as
       the X Toolkit provides standard options that accomplish the same  task.

       %geom   This  option  specifies  the preferred size and position of the
               Tektronix window.  It is shorthand for specifying the ''*tekGe-
               ometry'' resource.

        #geom  This  option  specifies the preferred position of the icon win-
               dow.  It is  shorthand  for  specifying  the  ''*iconGeometry''
               resource.

       -T string
               This  option  specifies  the  title for xterm's windows.  It is
               equivalent to -title.

       -n string
               This option specifies the icon name for xterm's windows.  It is
               shorthand for specifying the ''*iconName'' resource.  Note that
               this is not the same as the toolkit option -name  (see  below).
               The default icon name is the application name.

       -r      This option indicates that reverse video should be simulated by
               swapping the foreground and background colors.  It  is  equiva-
               lent to -rv.

       -w number
               This  option  specifies  the width in pixels of the border sur-
               rounding the window.  It is equivalent to -borderwidth or  -bw.

       The  following  standard  X Toolkit command line arguments are commonly
       used with xterm:

       -bd color
               This option specifies the color to use for the  border  of  the
               window.   xterm  uses  the  X Toolkit default, which is ''XtDe-
               faultForeground''.

       -bg color
               This option specifies the color to use for  the  background  of
               the window.  The default is ''XtDefaultBackground.''

       -bw number
               This  option  specifies  the width in pixels of the border sur-
               rounding the window.

       -display display
               This  option  specifies  the   X   server   to   contact;   see
               X(el5_4.1-root-mockbuild/usr/share/man/xterm.1).

       -fg color
               This  option  specifies  the  color to use for displaying text.
               The default is ''XtDefaultForeground.''

       -fn font
               This option specifies the font to be used for displaying normal
               text.  The default is fixed.

       -font font
               This is the same as -fn.

       -geometry geometry
               This  option  specifies  the preferred size and position of the
               VT102         window;         see          X(el5_4.1-root-mock-
               build/usr/share/man/xterm.1).

       -iconic This  option indicates that xterm should ask the window manager
               to start it as an icon rather than as the normal window.

       -name name
               This  option  specifies  the  application  name   under   which
               resources  are  to  be  obtained,  rather than the default exe-
               cutable file name.  Name should  not  contain  ''.''  or  ''*''
               characters.

       -rv     This option indicates that reverse video should be simulated by
               swapping the foreground and background colors.

       +rv     Disable the simulation of reverse video by swapping  foreground
               and background colors.

       -title string
               This  option  specifies  the  window title string, which may be
               displayed by window managers  if  the  user  so  chooses.   The
               default  title  is  the  command  line  specified  after the -e
               option, if any, otherwise the application name.

       -xrm resourcestring
               This option specifies a resource string to be  used.   This  is
               especially  useful for setting resources that do not have sepa-
               rate command line options.

RESOURCES
       The program understands all of the core X Toolkit  resource  names  and
       classes.  Application specific resources (e.g., "XTerm.NAME") follow:

       backarrowKeyIsErase (class BackarrowKeyIsErase)
               Tie   the  VTxxx  backarrowKey  and  ptyInitialErase  resources
               together by setting the DECBKM state according to  whether  the
               initial  value of stty erase is a backspace (8) or delete (127)
               character.  The default is ''false'', which disables this  fea-
               ture.

       hold (class Hold)
               If true, xterm will not immediately destroy its window when the
               shell command completes.  It will wait until you use the window
               manager  to  destroy/kill  the  window,  or if you use the menu
               entries that send a signal, e.g., HUP or KILL.  You may  scroll
               back,  select text, etc., to perform most graphical operations.
               Resizing the  display  will  lose  data,  however,  since  this
               involves interaction with the shell which is no longer running.

       hpFunctionKeys (class HpFunctionKeys)
               Specifies whether or not HP Function Key escape codes should be
               generated   for   function  keys  instead  of  standard  escape
               sequences.  See also the keyboardType resource.

       iconGeometry (class IconGeometry)
               Specifies the preferred size and position  of  the  application
               when  iconified.   It  is  not necessarily obeyed by all window
               managers.

       iconName (class IconName)
               Specifies the icon name.  The default is the application  name.

       keyboardType (class KeyboardType)
               Enables  one  (or none) of the various keyboard-type resources:
               hpFunctionKeys, scoFunctionKeys,  sunFunctionKeys  and  sunKey-
               board.  The resource's value should be one of the corresponding
               strings hp, sco, sun or vt220.  The  individual  resources  are
               provided for legacy support; this resource is simpler to use.

       maxBufSize (class MaxBufSize)
               Specify  the  maximum size of the input buffer.  The default is
               32768.  You cannot set this to a value less than the minBufSize
               resource.   It  will  be increased as needed to make that value
               evenly divide this one.

               On some systems you may want to increase one  or  both  of  the
               maxBufSize  and  minBufSize  resource  values to achieve better
               performance if  the  operating  system  prefers  larger  buffer
               sizes.

       messages (class Messages)
               Specifies  whether write access to the terminal is allowed ini-
               tially.  See mesg(1).  The default is ''true''.

       minBufSize (class MinBufSize)
               Specify the minimum size of the input buffer, i.e., the  amount
               of data that xterm requests on each read.  The default is 4096.
               You cannot set this to a value less than 64.

       ptyHandshake (class PtyHandshake)
               If ''true'', xterm will perform handshaking during  initializa-
               tion  to  ensure that the parent and child processes update the
               utmp and stty state.  The default is ''true''.

       ptyInitialErase (class PtyInitialErase)
               If ''true'', xterm will use the pseudo-terminal's sense of  the
               stty  erase value.  If ''false'', xterm will set the stty erase
               value to match its own configuration, using the kb string  from
               the  termcap  entry  as  a  reference, if available.  In either
               case, the result is applied to the TERMCAP variable which xterm
               sets.  The default is ''false''.

       sameName (class SameName)
               If  the value of this resource is ''true'', xterm does not send
               title and icon name change requests when the request would have
               no  effect: the name is not changed.  This has the advantage of
               preventing flicker and the disadvantage of requiring  an  extra
               round  trip  to  the server to find out the previous value.  In
               practice this should  never  be  a  problem.   The  default  is
               ''true''.

       scoFunctionKeys (class ScoFunctionKeys)
               Specifies  whether  or not SCP Function Key escape codes should
               be generated for  function  keys  instead  of  standard  escape
               sequences.  See also the keyboardType resource.

       sessionMgt (class SessionMgt)
               If  the  value of this resource is ''true'', xterm sets up ses-
               sion manager callbacks for XtNdieCallback and  XtNsaveCallback.
               The default is ''true''.

       sunFunctionKeys (class SunFunctionKeys)
               Specifies  whether  or not Sun Function Key escape codes should
               be generated for  function  keys  instead  of  standard  escape
               sequences.  See also the keyboardType resource.

       sunKeyboard (class SunKeyboard)
               Specifies  whether  or  not  Sun/PC  keyboard  layout should be
               assumed rather than DEC VT220.  This causes the keypad  '+'  to
               be mapped to ','.  and CTRL F1-F12 to F11-F20, depending on the
               setting of the ctrlFKeys resource.  so  xterm  emulates  a  DEC
               VT220  more  accurately.   Otherwise (the default, with sunKey-
               board set to ''false''), xterm uses PC-style bindings  for  the
               function keys and keypad.

               PC-style  bindings use the Shift, Alt, Control and Meta keys as
               modifiers for function-keys and keypad (see the document  Xterm
               Control  Sequences  for  details).   The  PC-style bindings are
               analogous to PCTerm, but not the same  thing.   Normally  these
               bindings  do  not  conflict  with  the  use  of the Meta key as
               described for the eightBitInput resource.   If  they  do,  note
               that  the  PC-style bindings are evaluated first.  See also the
               keyboardType resource.

       termName (class TermName)
               Specifies the terminal type name to be set in the TERM environ-
               ment variable.

       title (class Title)
               Specifies  a string that may be used by the window manager when
               displaying this application.

       toolBar (class ToolBar)
               Specifies whether or not the toolbar should be displayed.   The
               default is ''true.''

       ttyModes (class TtyModes)
               Specifies a string containing terminal setting keywords and the
               characters to which they  may  be  bound.   Allowable  keywords
               include:  brk,  dsusp,  eof,  eol,  eol2, erase, erase2, flush,
               intr, kill, lnext, quit,  rprnt,  start,  status,  stop,  susp,
               swtch  and weras.  Control characters may be specified as ^char
               (e.g., ^c or ^u) and ^? may be used to indicate  delete  (127).
               Use ^- to denote undef.  Use \034 to represent ^\, since a lit-
               eral backslash in an X resource escapes the next character.

               This is very useful for overriding the  default  terminal  set-
               tings  without  having  to  do  an  stty every time an xterm is
               started.  Note, however, that the stty program on a given  host
               may use different keywords; xterm's table is built-in.

       useInsertMode (class UseInsertMode)
               Force  use  of insert mode by adding appropriate entries to the
               TERMCAP environment variable.  This is  useful  if  the  system
               termcap is broken.  The default is ''false.''

       utmpDisplayId (class UtmpDisplayId)
               Specifies whether or not xterm should try to record the display
               identifier (display number and screen number) as  well  as  the
               hostname in the system utmp log file.  The default is ''true.''

       utmpInhibit (class UtmpInhibit)
               Specifies whether or not xterm should try to record the  user's
               terminal  in the system utmp log file.  If true, xterm will not
               try.  The default is ''false.''

       waitForMap (class WaitForMap)
               Specifies whether or not xterm should wait for the initial win-
               dow  map  before  starting  the  subprocess.   The  default  is
               ''false.''

       zIconBeep (class ZIconBeep)
               Same as -ziconbeep command line argument.  If the value of this
               resource  is  non-zero, xterms that produce output while iconi-
               fied will cause an XBell sound at the  given  volume  and  have
               "***"  prepended  to  their  icon titles.  Most window managers
               will detect this change immediately, showing you  which  window
               has  the  output.   (A  similar feature was in x10 xterm.)  The
               default is ''false.''

       The following resources are specified  as  part  of  the  vt100  widget
       (class    VT100):   These   are   specified   by   patterns   such   as
       "XTerm.vt100.NAME":

       activeIcon (class ActiveIcon)
               Specifies whether or not active icon windows  are  to  be  used
               when the xterm window is iconified, if this feature is compiled
               into xterm.  The active icon is a miniature  representation  of
               the  content  of  the  window  and  will  update as the content
               changes.  Not all window managers necessarily support  applica-
               tion  icon  windows.   Some  window  managers will allow you to
               enter keystrokes into the active icon window.  The  default  is
               ''false.''

       allowC1Printable (class AllowC1Printable)
               If  true,  overrides the mapping of C1 controls (codes 128-159)
               to make them be treated as if they were  printable  characters.
               Although this corresponds to no particular standard, some users
               insist it is a VT100.  The default is ''false.''

       allowSendEvents (class AllowSendEvents)
               Specifies whether or not synthetic key and button events  (gen-
               erated using the X protocol SendEvent request) should be inter-
               preted or discarded.  The default is ''false'' meaning they are
               discarded.  Note that allowing such events creates a very large
               security hole.  The default is ''false.''

       allowWindowOps (class AllowWindowOps)
               Specifies whether extended window control sequences (as used in
               dtterm) for should be allowed.  The default is ''true.''

       alwaysHighlight (class AlwaysHighlight)
               Specifies  whether  or  not xterm should always display a high-
               lighted text cursor.  By default (if this resource is false), a
               hollow  text cursor is displayed whenever the pointer moves out
               of the window or the window loses the input focus.  The default
               is ''false.''

       alwaysUseMods (class AlwaysUseMods)
               Override the numLock resource, telling xterm to use the Alt and
               Meta  modifiers  to  construct  parameters  for  function   key
               sequences  even  if  those modifiers appear in the translations
               resource.  The default is ''false.''

       answerbackString (class AnswerbackString)
               Specifies the string that xterm sends in  response  to  an  ENQ
               (control/E)  character  from  the host.  The default is a blank
               string, i.e., ''''.  A hardware VT100 implements  this  feature
               as a setup option.

       appcursorDefault (class AppcursorDefault)
               If ''true,'' the cursor keys are initially in application mode.
               This is the same as the VT102 private DECCKM mode, The  default
               is ''false.''

       appkeypadDefault (class AppkeypadDefault)
               If ''true,'' the keypad keys are initially in application mode.
               The default is ''false.''

       autoWrap (class AutoWrap)
               Specifies whether or not  auto-wraparound  should  be  enabled.
               This is the same as the VT102 DECAWM.  The default is ''true.''

       awaitInput (class AwaitInput)
               Specifies whether or not the xterm uses a 50 millisecond  time-
               out   to   await  input  (i.e.,  to  support  the  Xaw3d  arrow
               scrollbar).  The default is ''false.''

       backarrowKey (class BackarrowKey)
               Specifies whether the backarrow key transmits a  backspace  (8)
               or delete (127) character.  This corresponds to the DECBKM con-
               trol sequence.  The default (backspace) is ''true.''   Pressing
               the control key toggles this behavior.

       background (class Background)
               Specifies  the  color  to use for the background of the window.
               The default is ''XtDefaultBackground.''

       bellOnReset (class BellOnReset)
               Specifies whether to sound a bell when doing a hard reset.  The
               default is ''true.''

       bellSuppressTime (class BellSuppressTime)
               Number  of  milliseconds  after  a  bell command is sent during
               which additional bells will be suppressed.  Default is 200.  If
               set  non-zero,  additional  bells will also be suppressed until
               the server reports that processing of the first bell  has  been
               completed; this feature is most useful with the visible bell.

       boldColors (class ColorMode)
               Specifies  whether  to  combine bold attribute with colors like
               the IBM PC, i.e., map colors 0 through 7 to  colors  8  through
               15.   These  normally  are the brighter versions of the first 8
               colors, hence bold.  The default is ''true.''

       boldFont (class BoldFont)
               Specifies the name of the bold font to  use  instead  of  over-
               striking.  There is no default for this resource.

       boldMode (class BoldMode)
               This  specifies  whether  or  not  text with the bold attribute
               should be overstruck to simulate bold  fonts  if  the  resolved
               bold  font is the same as the normal font.  It may be desirable
               to disable bold fonts when color is being  used  for  the  bold
               attribute.  Note that xterm has one bold font which you may set
               explicitly.  It attempts to match a bold  font  for  the  other
               font  selections (font1 through font6).  If the normal and bold
               fonts are distinct, this resource has no effect.   The  default
               is ''true.''

               Although  xterm  attempts  to  match a bold font for other font
               selections, the font server may not  cooperate.   Since  X11R6,
               bitmap  fonts have been scaled.  The font server claims to pro-
               vide the bold font that xterm requests, but the result  is  not
               always  readable.  XFree86 provides a feature which can be used
               to suppress the scaling.  In the X server's configuration  file
               (e.g.,  /etc/X11/xorg.conf), you can add ":unscaled" to the end
               of the directory specification for the "misc" fonts, which com-
               prise  the fixed-pitch fonts that are used by xterm.  For exam-
               ple
                    FontPath  "/usr/share/X11/fonts"

               would become
                    FontPath  "/usr/share/X11/fonts/misc/:unscaled"

               Depending on your configuration, the font server may  have  its
               own  configuration  file.  The same ":unscaled" can be added to
               its configuration file at the end of the  directory  specifica-
               tion for "misc".

       brokenLinuxOSC (class BrokenLinuxOSC)
               If true, xterm applies a workaround to ignore malformed control
               sequences that a Linux script might send.  Compare the  palette
               control  sequences  documented  in  console_codes with ECMA-48.
               The default is ''true.''

       brokenSelections (class BrokenSelections)
               If true, xterm in 8-bit mode will interpret  STRING  selections
               as  carrying  text  in the current locale's encoding.  Normally
               STRING selections carry ISO-8859-1 encoded text.  Setting  this
               resource  to  ''true''  violates the ICCCM; it may, however, be
               useful for interacting with some broken X clients.  The default
               is ''false.''

       brokenStringTerm (class BrokenStringTerm)
               provides  a  work-around  for  some ISDN routers which start an
               application control string without completing it.  Set this  to
               ''true''  if  xterm  appears  to  freeze  when connecting.  The
               default is ''false.''

       c132 (class C132)
               Specifies whether or not the  VT102  DECCOLM  escape  sequence,
               used  to  switch between 80 and 132 columns, should be honored.
               The default is ''false.''

       cacheDoublesize (class CacheDoublesize)
               Specifies the maximum number of double-sized  fonts  which  are
               cached  by  xterm.  The default (8) may be too large for some X
               terminals with limited memory.  Set this  to  zero  to  disable
               doublesize fonts altogether.

       charClass (class CharClass)
               Specifies  comma-separated lists of character class bindings of
               the form [low-]high:value.  These are used in determining which
               sets  of  characters  should be treated the same when doing cut
               and paste.  See the CHARACTER CLASSES section.

       cjkWidth (class CjkWidth)
               Specifies whether xterm  should  follow  the  traditional  East
               Asian  width  convention.  When turned on, characters with East
               Asian Ambiguous (A) category in UTR 11 have a column  width  of
               2.   You  may  have  to set this option to ''true'' if you have
               some old East Asian terminal based programs  that  assume  that
               line-drawing  characters have a column width of 2.  The default
               is ''false.''

       color0 (class Color0)

       color1 (class Color1)

       color2 (class Color2)

       color3 (class Color3)

       color4 (class Color4)

       color5 (class Color5)

       color6 (class Color6)

       color7 (class Color7)
               These specify the colors  for  the  ISO  6429  extension.   The
               defaults  are,  respectively,  black,  red3, green3, yellow3, a
               customizable dark  blue,  magenta3,  cyan3,  and  gray90.   The
               default  shades of color are chosen to allow the colors 8-15 to
               be used as brighter versions.

       color8 (class Color8)

       color9 (class Color9)

       color10 (class Color10)

       color11 (class Color11)

       color12 (class Color12)

       color13 (class Color13)

       color14 (class Color14)

       color15 (class Color15)
               These specify the colors for the ISO 6429 extension if the bold
               attribute  is  also  enabled.   The default resource values are
               respectively, gray30, red, green, yellow, a customizable  light
               blue, magenta, cyan, and white.

       color16 (class Color16)

       through

       color255 (class Color255)
               These  specify  the  colors  for  the 256-color extension.  The
               default resource values are for colors 16 through 231 to make a
               6x6x6  color  cube,  and  colors  232  through  255  to  make a
               grayscale ramp.

       colorAttrMode (class ColorAttrMode)
               Specifies whether colorBD, colorBL, colorRV, and colorUL should
               override ANSI colors.  If not, these are displayed only when no
               ANSI colors have been set for the corresponding position.   The
               default is ''false.''

       colorBD (class ColorBD)
               This  specifies  the color to use to display bold characters if
               the  ''colorBDMode''  resource  is  enabled.   The  default  is
               ''XtDefaultForeground.''

       colorBDMode (class ColorAttrMode)
               Specifies  whether characters with the bold attribute should be
               displayed in color or as bold characters.   Note  that  setting
               colorMode off disables all colors, including bold.  The default
               is ''false.''

       colorBL (class ColorBL)
               This specifies the color to use to display blink characters  if
               the  ''colorBLMode''  resource  is  enabled.   The  default  is
               ''XtDefaultForeground.''

       colorBLMode (class ColorAttrMode)
               Specifies whether characters with the blink attribute should be
               displayed  in  color.  Note that setting colorMode off disables
               all colors, including this.  The default is ''false.''

       colorMode (class ColorMode)
               Specifies whether or not recognition of ANSI (ISO  6429)  color
               change  escape  sequences  should  be  enabled.  The default is
               ''true.''

       colorRV (class ColorRV)
               This specifies the color to use to display  reverse  characters
               if  the  ''colorRVMode''  resource  is enabled.  The default is
               ''XtDefaultForeground.''

       colorRVMode (class ColorAttrMode)
               Specifies whether characters with the reverse attribute  should
               be  displayed  in  color.  Note that setting colorMode off dis-
               ables all colors, including this.  The default is ''false.''

       colorUL (class ColorUL)
               This specifies the color to use to display  underlined  charac-
               ters  if  the ''colorULMode'' resource is enabled.  The default
               is ''XtDefaultForeground.''

       colorULMode (class ColorAttrMode)
               Specifies  whether  characters  with  the  underline  attribute
               should be displayed in color or as underlined characters.  Note
               that setting  colorMode  off  disables  all  colors,  including
               underlining.  The default is ''false.''

       ctrlFKeys (class CtrlFKeys)
               In  VT220  keyboard  mode (see sunKeyboard resource), specifies
               the amount by which to shift F1-F12 given  a  control  modifier
               (CTRL).  This allows you to generate key symbols for F10-F20 on
               a Sun/PC keyboard.  The default is  ''10'',  which  means  that
               CTRL F1 generates the key symbol for F11.

       curses (class Curses)
               Specifies  whether or not the last column bug in more(1) should
               be worked around.  See the -cu option for details.  The default
               is ''false.''

       cursorBlink (class CursorBlink)
               Specifies  whether  to  make  the cursor blink.  The default is
               ''false.''

       cursorColor (class CursorColor)
               Specifies the color to use for the text cursor.  The default is
               ''XtDefaultForeground.''   Xterm  attempts  to  keep this color
               from being the same as the background color, since it draws the
               cursor  by  filling  the  background  of a text cell.  The same
               restriction applies to control sequences which may change  this
               color.

       cursorOffTime (class CursorOffTime)
               Specifies  the  duration  of the "off" part of the cursor blink
               cycle-time in milliseconds.  The same timer is  used  for  text
               blinking.  The default is 300.

       cursorOnTime (class CursorOnTime)
               Specifies  the  duration  of  the "on" part of the cursor blink
               cycle-time, in milliseconds.  The same timer is used  for  text
               blinking.  The default is 600.

       cutNewline (class CutNewline)
               If ''false'', triple clicking to select a line does not include
               the Newline at the end of the line.  If ''true'',  the  Newline
               is selected.  The default is ''true.''

       cutToBeginningOfLine (class CutToBeginningOfLine)
               If  ''false'',  triple  clicking  to select a line selects only
               from the current word forward.  If ''true'', the entire line is
               selected.  The default is ''true.''

       decTerminalID (class DecTerminalID)
               Specifies  the  emulation  level  (100=VT100, 220=VT220, etc.),
               used to  determine  the  type  of  response  to  a  DA  control
               sequence.   Leading  non-digit  characters  are  ignored, e.g.,
               "vt100" and "100" are the same.  The default is 100.

       deleteIsDEL (class DeleteIsDEL)
               Specifies whether the Delete key on the editing  keypad  should
               send  DEL (127) or the VT220-style Remove escape sequence.  The
               default is ''false,'' for the latter.

       dynamicColors (class DynamicColors)
               Specifies whether or not  escape  sequences  to  change  colors
               assigned to different attributes are recognized.

       eightBitControl (class EightBitControl)
               Specifies whether or not control sequences sent by the terminal
               should  be  eight-bit  characters  or  escape  sequences.   The
               default is ''false.''

       eightBitInput (class EightBitInput)
               If  ''true'', Meta characters (a single-byte character combined
               with the keys modifier key) input from the  keyboard  are  pre-
               sented  as  a  single  character with the eighth bit turned on.
               The terminal is put into 8-bit mode.  If ''false'', Meta  char-
               acters  are  converted  into  a two-character sequence with the
               character itself preceded by ESC.  On startup, xterm  tries  to
               put the terminal into 7-bit mode.  The metaSendsEscape resource
               may override this.  The default is ''true.''

               Generally keyboards do not have a key labeled "Meta", but "Alt"
               keys  are  common, and they are conventionally used for "Meta".
               If they were synonymous, it would have been reasonable to  name
               this  resource "altSendsEscape", reversing its sense.  For more
               background on this, see the meta function in curses.

               Note that the Alt key is not necessarily the same as  the  Meta
               modifier.   xmodmap  lists your key modifiers.  X defines modi-
               fiers for shift, (caps) lock and control, as well  as  5  addi-
               tional modifiers which are generally used to configure key mod-
               ifiers.  xterm inspects the same information to find the  modi-
               fier  associated with either Meta key (left or right), and uses
               that key as the Meta modifier.  It also looks for  the  NumLock
               key, to recognize the modifier which is associated with that.

               If  your  xmodmap configuration uses the same keycodes for Alt-
               and Meta-keys, xterm will only  see  the  Alt-key  definitions,
               since  those  are  tested  before Meta-keys.  NumLock is tested
               first.  It is important to keep these keys distinct;  otherwise
               some of xterm's functionality is not available.

       eightBitOutput (class EightBitOutput)
               Specifies  whether  or  not  eight-bit characters sent from the
               host should be accepted as is or stripped  when  printed.   The
               default  is ''true,'' which means that they are accepted as is.

       faceName (class FaceName)
               Specify the  pattern  for  fonts  selected  from  the  FreeType
               library  if  support  for that library was compiled into xterm.
               There is no default.  If not specified, or if there is no match
               for both normal and bold fonts, xterm uses the font and related
               resources.

       faceNameDoublesize (class FaceNameDoublesize)
               Specify an double-width font for  cases  where  an  application
               requires this, e.g., in CJK applications.  There is no default.
               If  the  application  uses  double-wide  characters  and   this
               resource  is not given, xterm  will use a scaled version of the
               font given by faceName.

       faceSize (class FaceSize)
               Specify the pointsize for  fonts  selected  from  the  FreeType
               library  if  support  for that library was compiled into xterm.
               The default is ''14.''

       font (class Font)
               Specifies  the  name  of  the  normal  font.   The  default  is
               ''fixed.''

               See  the discussion of the locale resource, which describes how
               this font may be overridden.

               NOTE: some resource files use patterns such as
               *font: fixed

               which are overly broad, affecting both
               xterm.vt100.font

               and
               xterm.vt100..utf8fonts.font

               which is probably not what you intended.

       font1 (class Font1)
               Specifies the name of the first alternative font.

       font2 (class Font2)
               Specifies the name of the second alternative font.

       font3 (class Font3)
               Specifies the name of the third alternative font.

       font4 (class Font4)
               Specifies the name of the fourth alternative font.

       font5 (class Font5)
               Specifies the name of the fifth alternative font.

       font6 (class Font6)
               Specifies the name of the sixth alternative font.

       fontDoublesize (class FontDoublesize)
               Specifies whether xterm should attempt to use font  scaling  to
               draw  doublesize characters.  Some older font servers cannot do
               this  properly,  will  return  misleading  font  metrics.   The
               default  is ''true''.  If disabled, xterm will simulate double-
               size  characters  by  drawing  normal  characters  with  spaces
               between them.

       forceBoxChars (class ForceBoxChars)
               Specifies whether xterm should assume the normal and bold fonts
               have VT100 line-drawing characters:

               -    The fixed-pitch ISO-8859-*-encoded  fonts  used  by  xterm
                    normally have the VT100 line-drawing glyphs in cells 1-31.
                    Other fixed-pitch fonts may be more attractive,  but  lack
                    these glyphs.

               -    When  using an ISO-10646-1 font and the wideChars resource
                    is true, xterm uses the Unicode  glyphs  which  match  the
                    VT100 line-drawing glyphs.

               If  ''false'',  xterm checks for missing glyphs in the font and
               makes line-drawing characters directly as needed.  If ''true'',
               xterm  uses  whatever  is  in  the  font without checking.  The
               default is ''false.''

       foreground (class Foreground)
               Specifies the color to use for displaying text in  the  window.
               Setting  the class name instead of the instance name is an easy
               way to have everything that would normally appear in  the  text
               color change color.  The default is ''XtDefaultForeground.''

       freeBoldBox (class freeBoldBox)
               Specifies  whether  xterm  should assume the bounding boxes for
               normal and bold fonts are compatible.  If ''false'', xterm com-
               pares  them  and  will reject choices of bold fonts that do not
               match the size of the normal font.  The default  is  ''false'',
               which means that the comparison is performed.

       geometry (class Geometry)
               Specifies  the preferred size and position of the VT102 window.
               There is no default for this resource.

       highlightColor (class HighlightColor)
               Specifies the color to use for the background  of  selected  or
               otherwise highlighted text.  If not specified, reverse video is
               used.  The default is ''XtDefaultForeground.''

       highlightSelection (class HighlightSelection)
               If ''false'', selecting with the mouse highlights all positions
               on  the  screen  between the beginning of the selection and the
               current position.  If ''true'', xterm highlights only the posi-
               tions  that  contain text that can be selected.  The default is
               ''false.''

               Depending on the way your applications  write  to  the  screen,
               there  may  be trailing blanks on a line.  Xterm stores data as
               it is shown on the screen.  Erasing  the  display  changes  the
               internal state of each cell so it is not considered a blank for
               the purpose of selection.  Blanks written since the last  erase
               are  selectable.  If you do not wish to have trailing blanks in
               a selection, use the trimSelection resource.

       hpLowerleftBugCompat (class HpLowerleftBugCompat)
               Specifies whether to work around  a  bug  in  HP's  xdb,  which
               ignores  termcap  and  always  sends ESC F to move to the lower
               left corner.  ''true'' causes xterm to interpret  ESC  F  as  a
               request  to  move  to the lower left corner of the screen.  The
               default is ''false.''

       i18nSelections (class I18nSelections)
               If false, xterm will never request the targets COMPOUND_TEXT or
               TEXT.  The default is ''true.'' It may be set to false in order
               to work around ICCCM violations by other X clients.

       iconBorderColor (class BorderColor)
               Specifies the border color for the active icon window  if  this
               feature  is  compiled into xterm.  Not all window managers will
               make the icon border visible.

       iconBorderWidth (class BorderWidth)
               Specifies the border width for the active icon window  if  this
               feature  is  compiled  into  xterm.  The default is 2.  Not all
               window managers will make the border visible.

       iconFont (class IconFont)
               Specifies the font for the miniature  active  icon  window,  if
               this feature is compiled into xterm.  The default is "nil2".

       internalBorder (class BorderWidth)
               Specifies  the  number of pixels between the characters and the
               window border.  The default is 2.

       italicULMode (class ColorAttrMode)
               Specifies  whether  characters  with  the  underline  attribute
               should  be displayed in an italic font or as underlined charac-
               ters.

       jumpScroll (class JumpScroll)
               Specifies whether or not jump scroll should be used.  This cor-
               responds  to  the  VT102  DECSCLM private mode.  The default is
               ''true.''

       keyboardDialect (class KeyboardDialect)
               Specifies the initial keyboard dialect, as well as the  default
               value  when the terminal is reset.  The value given is the same
               as the final character in the control  sequences  which  change
               character  sets.  The default is ''B'', which corresponds to US
               ASCII.

       nameKeymap (class NameKeymap)
               See the discussion of the keymap() action.

       limitResize (class LimitResize)
               Limits resizing of the screen via control sequence to  a  given
               multiple of the display dimensions.  The default is ''1''.

       locale (class Locale)
               Specifies  how to use luit, an encoding converter between UTF-8
               and locale encodings.  The resource value (ignoring  case)  may
               be:

               true
                   xterm  will  use  the  encoding  specified  by  the  users'
                   LC_CTYPE locale (i.e., LC_ALL, LC_CTYPE, or LANG variables)
                   as  far  as  possible.  This is realized by always enabling
                   UTF-8 mode and invoking luit in non-UTF-8 locales.

               medium
                   xterm will follow users' LC_CTYPE locale  only  for  UTF-8,
                   east  Asian, and Thai locales, where the encodings were not
                   supported by conventional 8bit mode  with  changing  fonts.
                   For other locales, xterm will use conventional 8bit mode.

               checkfont
                   If  mini-luit is compiled-in, xterm will check if a Unicode
                   font has been specified.  If so, it checks if the character
                   encoding  for  the  current  locale  is  POSIX,  Latin-1 or
                   Latin-9, uses the appropriate mapping to support those with
                   the  Unicode font.  For other encodings, xterm assumes that
                   UTF-8 encoding is required.

               false
                   xterm will use conventional 8bit mode or UTF-8 mode accord-
                   ing to utf8 resource or -u8 option.

               Any  other  value, e.g., ''UTF-8'' or ''ISO8859-2'', is assumed
               to be an encoding name; luit will be  invoked  to  support  the
               encoding.   The  actual  list of supported encodings depends on
               luit.  The default is ''medium''.

               Regardless of your locale and encoding, you need an ISO-10646-1
               font to display the result.  Your configuration may not include
               this font, or locale-support by xterm may not  be  needed.   At
               startup,  xterm  uses  a  mechanism  equivalent to the load-vt-
               fonts(utf8Fonts, Utf8Fonts) action to  load  font  name  subre-
               sources  of  the VT100 widget.  That is, resource patterns such
               as  "*vt100.utf8Fonts.font"  will  be  loaded,  and  (if   this
               resource  is enabled), override the normal fonts.  If no subre-
               sources are found, the  normal  fonts  such  as  "*vt100.font",
               etc.,  are used.  The resource files distributed with xterm use
               ISO-10646-1 fonts, but do not rely on them unless you are using
               the locale mechanism.

       localeFilter (class LocaleFilter)
               Specifies  the  file  name  for  the encoding converter from/to
               locale encodings and UTF-8 which is used with the -lc option or
               locale  resource.   The  help  message shown by ''xterm -help''
               lists the default value, which depends on your system  configu-
               ration.

       loginShell (class LoginShell)
               Specifies  whether  or  not  the  shell to be run in the window
               should be started as a login shell.  The default is  ''false.''

       marginBell (class MarginBell)
               Specifies  whether or not the bell should be rung when the user
               types near the right margin.  The default is ''false.''

       metaSendsEscape (class MetaSendsEscape)
               If ''true'', Meta characters (a  character  combined  with  the
               Meta  modifier key) are converted into a two-character sequence
               with the character itself preceded by  ESC.   This  applies  as
               well  to function key control sequences, unless xterm sees that
               Meta is used in your  key  translations.   If  ''false'',  Meta
               characters input from the keyboard are handled according to the
               eightBitInput resource.  The default is ''false.''

       mkWidth (class MkWidth)
               Specifies whether xterm should use a built-in  version  of  the
               wide character width calculation.  The default is ''false.''

       modifyCursorKeys (class ModifyCursorKeys)
               Tells  how  to  handle the special case where Control-, Shift-,
               Alt- or Meta-modifiers are used  to  add  a  parameter  to  the
               escape  sequence  returned  by  a  cursor-key.   The default is
               ''2'':

               Set it to 0 to use the old/obsolete behavior.
               Set it to 1 to prefix modified sequences with CSI.
               Set it to 2 to force the modifier to be the second parameter.
               Set it to 3 to mark the sequence with a '>' to hint that it  is
               private.

       modifyOtherKeys (class ModifyOtherKeys)
               Like  modifyCursorKeys,  tells  xterm  to  construct  an escape
               sequence for other keys (such as "2")  when  modified  by  Con-
               trol-,  Alt- or Meta-modifiers.  This feature does not apply to
               function keys and well-defined keys such as ESC or the  control
               keys.  The default is ''0'':

               Set it to 0 to disable this feature.
               Set it to 1 to enable this feature for keys except Tab and some
               special control character cases, e.g., Control-Space to make  a
               NUL.
               Set  it  to  1  to  enable  this feature for keys including the
               exceptions listed.

       multiClickTime (class MultiClickTime)
               Specifies the maximum time in milliseconds between  multi-click
               select events.  The default is 250 milliseconds.

       multiScroll (class MultiScroll)
               Specifies  whether  or  not  scrolling  should  be  done  asyn-
               chronously.  The default is ''false.''

       nMarginBell (class Column)
               Specifies the number of characters from  the  right  margin  at
               which the margin bell should be rung, when enabled.

       numLock (class NumLock)
               If ''true'', xterm checks if NumLock is used as a modifier (see
               xmodmap(1)).  If so, this modifier  is  used  to  simplify  the
               logic  when  implementing  special  NumLock for the sunKeyboard
               resource.  Also (when sunKeyboard is false), similar  logic  is
               used  to  find  the modifier associated with the left and right
               Alt keys.  The default is ''true.''

       oldXtermFKeys (class OldXtermFKeys)
               If ''true'', xterm will use  old-style  control  sequences  for
               function  keys  F1  to  F4, for compatibility with X Consortium
               xterm.  Otherwise, it uses the VT100-style  codes  for  PF1  to
               PF4.  The default is ''false.''

       on2Clicks (class On2Clicks)

       on3Clicks (class On3Clicks)

       on4Clicks (class On4Clicks)

       on5Clicks (class On5Clicks)
               Specify  selection  behavior  in  response  to  multiple  mouse
               clicks.   A  single  mouse  click  is  always  interpreted   as
               described in the SELECTION section (see POINTER USAGE).  Multi-
               ple mouse clicks (using the button which activates the  select-
               start  action) are interpreted according to the resource values
               of on2Clicks, etc.  The resource value can be one of these:

               word
                  Select a ''word'' as determined by the  charClass  resource.
                  See the CHARACTER CLASSES section.

               line
                  Select a line (counting wrapping).

               group
                  Select  a  group of adjacent lines (counting wrapping).  The
                  selection stops on a blank line.

               page
                  Select all visible lines, i.e., the page.

               all
                  Select all lines, i.e., including the saved lines.

               regex
                  Select a ''word'' as determined by  the  regular  expression
                  which follows in the resource value.

               none
                  No selection action is associated with this resource.  xterm
                  interprets it as the end of the list.  For example, you  may
                  use  it  to  disable triple (and higher) clicking by setting
                  on3Clicks to ''none''.

               The default values for on2Clicks and on3Clicks are ''word'' and
               ''line'',   respectively.    There  is  no  default  value  for
               on4Clicks or on5Clicks, making  those  inactive.   On  startup,
               xterm  determines the maximum number of clicks by the onXClicks
               resource values which are set.

       pointerColor (class PointerColor)
               Specifies the foreground color of the pointer.  The default  is
               ''XtDefaultForeground.''

       pointerColorBackground (class PointerColorBackground)
               Specifies  the background color of the pointer.  The default is
               ''XtDefaultBackground.''

       pointerShape (class Cursor)
               Specifies the name of the shape of the pointer.  The default is
               ''xterm.''

       popOnBell (class PopOnBell)
               Specifies  whether the window would be raised when Control-G is
               received.  The default is ''false.''

       printAttributes (class PrintAttributes)
               Specifies whether to print graphic attributes  along  with  the
               text.   A  real  DEC  VTxxx  terminal will print the underline,
               highlighting codes but your printer may not  handle  these.   A
               ''0''  disables  the attributes.  A ''1'' prints the normal set
               of  attributes  (bold,  underline,  inverse   and   blink)   as
               VT100-style  control  sequences.   A  ''2''  prints  ANSI color
               attributes as well.  The default is ''1.''

       printerAutoClose (class PrinterAutoClose)
               If ''true'', xterm will close the printer  (a  pipe)  when  the
               application switches the printer offline with a Media Copy com-
               mand.  The default is ''false.''

       printerCommand (class PrinterCommand)
               Specifies a shell command to which xterm will open a pipe  when
               the first MC (Media Copy) command is initiated.  The default is
               a blank string.  If the resource value  is  given  as  a  blank
               string, the printer is disabled.

       printerControlMode (class PrinterControlMode)
               Specifies  the printer control mode.  A ''1'' selects autoprint
               mode, which causes xterm to print a line from the  screen  when
               you  move  the cursor off that line with a line feed, form feed
               or vertical tab character, or an  autowrap  occurs.   Autoprint
               mode  is overridden by printer controller mode (a ''2''), which
               causes all of the output to be directed to  the  printer.   The
               default is ''0.''

       printerExtent (class PrinterExtent)
               Controls  whether  a  print page function will print the entire
               page (true), or only the the portion within the scrolling  mar-
               gins (false).  The default is ''false.''

       printerFormFeed (class PrinterFormFeed)
               Controls  whether a form feed is sent to the printer at the end
               of a print page function.  The default is ''false.''

       renderFont (class RenderFont)
               If xterm is built with the Xft library, this  controls  whether
               the faceName resource is used.  The default is ''true.''

       resizeGravity (class ResizeGravity)
               Affects the behavior when the window is resized to be taller or
               shorter.  NorthWest specifies that the top line of text on  the
               screen  stay  fixed.   If the window is made shorter, lines are
               dropped from the bottom; if the window is  made  taller,  blank
               lines  are  added  at  the bottom.  This is compatible with the
               behavior in R4.  SouthWest (the  default)  specifies  that  the
               bottom line of text on the screen stay fixed.  If the window is
               made taller, additional saved lines will be scrolled down  onto
               the  screen;  if  the  window  is  made  shorter, lines will be
               scrolled off the top of the screen, and  the  top  saved  lines
               will be dropped.

       reverseVideo (class ReverseVideo)
               Specifies  whether  or  not  reverse video should be simulated.
               The default is ''false.''

       reverseWrap (class ReverseWrap)
               Specifies whether or not reverse-wraparound should be  enabled.
               This  corresponds  to  xterm's private mode 45.  The default is
               ''false.''

       rightScrollBar (class RightScrollBar)
               Specifies whether or not the scrollbar should be  displayed  on
               the right rather than the left.  The default is ''false.''

       saveLines (class SaveLines)
               Specifies  the  number  of  lines to save beyond the top of the
               screen when a scrollbar is turned on.  The default is 64.

       scrollBar (class ScrollBar)
               Specifies whether or not the  scrollbar  should  be  displayed.
               The default is ''false.''

       scrollBarBorder (class ScrollBarBorder)
               Specifies the width of the scrollbar border.  Note that this is
               drawn to overlap the border of the xterm window.  Modifying the
               scrollbar's border affects only the line between the VT100 wid-
               get and the scrollbar.  The default value is 1.

       scrollKey (class ScrollCond)
               Specifies whether or not pressing a  key  should  automatically
               cause  the  scrollbar  to  go  to  the  bottom of the scrolling
               region.  This corresponds to xterm's private  mode  1011.   The
               default is ''false.''

       scrollLines (class ScrollLines)
               Specifies  the number of lines that the scroll-back and scroll-
               forw actions should use as a default.  The default value is  1.

       scrollTtyOutput (class ScrollCond)
               Specifies whether or not output to the terminal should automat-
               ically cause the scrollbar to go to the bottom of the scrolling
               region.  The default is ''true.''

       selectToClipboard (class SelectToClipboard)
               Tells  xterm whether to use the PRIMARY or CLIPBOARD for SELECT
               tokens in the selection mechanism.  The set-select  action  can
               change this at runtime, allowing the user to work with programs
               that handle only one  of  these  mechanisms.   The  default  is
               ''false'', which tells it to use PRIMARY.

       shiftFonts (class ShiftFonts)
               Specifies  whether  to  enable the actions larger-vt-font() and
               smaller-vt-font(), which are  normally  bound  to  the  shifted
               KP_Add and KP_Subtract.  The default is ''true.''

       showBlinkAsBold (class ShowBlinkAsBold)
               Tells  xterm  whether  to display text with blink-attribute the
               same as bold.  If xterm has  not  been  configured  to  support
               blinking  text,  the default is ''true.'', which corresponds to
               older versions of xterm, otherwise the default is ''false.''

       showMissingGlyphs (class ShowMissingGlyphs)
               Tells xterm whether to display a box outlining places  where  a
               character  has been used that the font does not represent.  The
               default is ''false.''

       signalInhibit (class SignalInhibit)
               Specifies whether or not the entries in  the  ''Main  Options''
               menu  for  sending  signals to xterm should be disallowed.  The
               default is ''false.''

       tekGeometry (class Geometry)
               Specifies the preferred size and position of the Tektronix win-
               dow.  There is no default for this resource.

       tekInhibit (class TekInhibit)
               Specifies whether or not the escape sequence to enter Tektronix
               mode should be ignored.  The default is ''false.''

       tekSmall (class TekSmall)
               Specifies whether or not the Tektronix mode window should start
               in its smallest size if no explicit geometry is given.  This is
               useful when running xterm on displays with small screens.   The
               default is ''false.''

       tekStartup (class TekStartup)
               Specifies  whether  or  not  xterm should start up in Tektronix
               mode.  The default is ''false.''

       tiXtraScroll (class TiXtraScroll)
               Specifies whether xterm should scroll to a new page  when  pro-
               cessing  the ti termcap entry, i.e., the private modes 47, 1047
               or 1049.  This is only in effect if  titeInhibit  is  ''true'',
               because  the  intent  of this option is to provide a picture of
               the full-screen application's display on the scrollback without
               wiping  out the text that would be shown before the application
               was initialized.  The default for this resource is ''false.''

       titeInhibit (class TiteInhibit)
               Specifies whether or not xterm should remove ti and te  termcap
               entries (used to switch between alternate screens on startup of
               many screen-oriented programs) from  the  TERMCAP  string.   If
               set,  xterm  also  ignores the escape sequence to switch to the
               alternate screen.  Xterm supports terminfo in a different  way,
               supporting  composite  control sequences (also known as private
               modes) 1047, 1048 and 1049 which have the same  effect  as  the
               original 47 control sequence.  The default for this resource is
               ''false.''

       translations (class Translations)
               Specifies the key and button bindings  for  menus,  selections,
               ''programmed  strings,'' etc.  The translations resource, which
               provides much of xterm's configurability, is a feature of the X
               Toolkit Intrinsics library (Xt).  See the ACTIONS section.

       trimSelection (class TrimSelection)
               If  you  set  highlightSelection, you can see the text which is
               selected, including any trailing spaces.  Clearing  the  screen
               (or  a  line)  resets it to a state containing no spaces.  Some
               lines may contain trailing spaces when  an  application  writes
               them  to  the screen.  However, you may not wish to paste lines
               with trailing spaces.  If this resource  is  true,  xterm  will
               trim  trailing spaces from text which is selected.  It does not
               affect spaces which result in a wrapped line, nor will it  trim
               the  trailing  newline  from  your  selection.   The default is
               ''false.''

       underLine (class UnderLine)
               This specifies whether or not text with the underline attribute
               should be underlined.  It may be desirable to disable underlin-
               ing when color is being used for the underline attribute.   The
               default is ''true.''

       utf8 (class Utf8)
               This  specifies  whether  xterm will run in UTF-8 mode.  If you
               set this resource, xterm also sets the wideChars resource as  a
               side-effect.   The  resource  is  an integer, expected to range
               from 0 to 3:

               0  UTF-8 mode is initially off.  The  command-line  option  +u8
                  sets the resource to this value.  Escape sequences for turn-
                  ing UTF-8 mode on/off are allowed.

               1  UTF-8 mode is initially on.  Escape  sequences  for  turning
                  UTF-8 mode on/off are allowed.

               2  The command-line option -u8 sets the resource to this value.
                  Escape sequences for turning UTF-8 mode on/off are  ignored.

               3  This  is  the  default value of the resource.  It is changed
                  during  initialization  depending  on  whether  the   locale
                  resource  was  set,  to 0 or 2.  See the locale resource for
                  additional discussion of non-UTF-8 locales.

               If you want to set the value of utf8,  it  should  be  in  this
               range.   Other  nonzero  values  are treated the same as ''1'',
               i.e., UTF-8 mode is initially  on,  and  escape  sequences  for
               turning UTF-8 mode on/off are allowed.

       utf8Fonts (class Utf8Fonts)
               See the discussion of the locale resource.

       utf8Latin1 (class Utf8Latin1)
               If true, allow an ISO-8859-1 normal font to be combined with an
               ISO-10646 font if the latter is given via the -fw option or its
               corresponding resource value.  The default is ''false.''

       utf8Title (class Utf8Title)
               Applications  can  set  xterm's  title  by  writing  a  control
               sequence.  Normally this control  sequence  follows  the  VT220
               convention,  which  encodes the string in ISO-8859-1 and allows
               for an 8-bit string terminator.  If xterm is started in a UTF-8
               locale,  it  translates  the ISO-8859-1 string to UTF-8 to work
               with the X libraries which assume the string is UTF-8.

               However, some users may wish to write a title string encoded in
               UTF-8.   Set  this  resource to ''true'' to allow UTF-8 encoded
               title strings.  That cancels the translation to UTF-8, allowing
               UTF-8 strings to be displayed as is.

               The default is ''false.''

       veryBoldColors (class VeryBoldColors)
               Specifies whether to combine video attributes with colors spec-
               ified by colorBD, colorBL, colorRV and colorUL.   The  resource
               value is the sum of values for each attribute:
                 1 for reverse,
                 2 for underline,
                 4 for bold and
                 8 for blink.

               The default is ''0.''

       visualBell (class VisualBell)
               Specifies whether or not a visible bell (i.e., flashing) should
               be used instead of an audible bell when Control-G is  received.
               The default is ''false.''

       visualBellDelay (class VisualBellDelay)
               Number  of milliseconds to delay when displaying a visual bell.
               Default is 100.  If set to zero, no visual bell  is  displayed.
               This  is useful for very slow displays, e.g., an LCD display on
               a laptop.

       vt100Graphics (class VT100Graphics)
               This specifies whether xterm will interpret VT100 graphic char-
               acter  escape  sequences  while  in UTF-8 mode.  The default is
               ''true'', to provide support for various legacy applications.

       wideBoldFont (class WideBoldFont)
               This option specifies the font to be used for  displaying  bold
               wide  text.  By default, it will attempt to use a font twice as
               wide as the font that will be used to draw bold  text.   If  no
               doublewidth font is found, it will improvise, by stretching the
               bold font.

       wideChars (class WideChars)
               Specifies if xterm should respond  to  control  sequences  that
               process 16-bit characters.  The default is ''false.''

       wideFont (class WideFont)
               This  option  specifies the font to be used for displaying wide
               text.  By default, it will attempt to use a font twice as  wide
               as  the font that will be used to draw normal text.  If no dou-
               blewidth font is found, it will improvise,  by  stretching  the
               normal font.

       ximFont (class XimFont)
               This  option  specifies  the font to be used for displaying the
               preedit string in the "OverTheSpot" input method.

               In "OverTheSpot"  preedit  type,  the  preedit  (preconversion)
               string  is  displayed at the position of the cursor.  It is the
               XIM server's responsibility to display the preedit string.  The
               XIM  client  must inform the XIM server of the cursor position.
               For best results, the preedit string must be displayed  with  a
               proper  font.   Therefore,  xterm informs the XIM server of the
               proper font.  The font is be supplied  by  a  "fontset",  whose
               default  value  is "*".  This matches every font, the X library
               automatically chooses fonts with proper charsets.  The  ximFont
               resource is provided to override this default font setting.

       The  following  resources  are  specified as part of the tek4014 widget
       (class  Tek4014).   These   are   specified   by   patterns   such   as

       ginTerminator (class GinTerminator)
               Specifies  what character(s) should follow a GIN report or sta-
               tus report.  The possibilities are  ''none,''  which  sends  no
               terminating   characters,   ''CRonly,''  which  sends  CR,  and
               ''CR&EOT,'' which sends  both  CR  and  EOT.   The  default  is
               ''none.''

       height (class Height)
               Specifies the height of the Tektronix window in pixels.

       initialFont (class InitialFont)
               Specifies  which  of the four Tektronix fonts to use initially.
               Values are the  same  as  for  the  set-tek-text  action.   The
               default is ''large.''

       width (class Width)
               Specifies the width of the Tektronix window in pixels.

       The  following  resources  are  useful  when  specified  for the Athena
       Scrollbar widget:

       thickness (class Thickness)
               Specifies the width in pixels of the scrollbar.

       background (class Background)
               Specifies the color to use for the background of the scrollbar.

       foreground (class Foreground)
               Specifies the color to use for the foreground of the scrollbar.
               The ''thumb'' of the scrollbar is a simple checkerboard pattern
               alternating pixels for foreground and background color.

POINTER USAGE
       Once  the  VT102 window is created, xterm allows you to select text and
       copy it within the same or other windows.

   SELECTION
       The selection functions are invoked when the pointer buttons  are  used
       with  no modifiers, and when they are used with the ''shift'' key.  The
       assignment of the functions described below to keys and buttons may  be
       changed through the resource database; see ACTIONS below.

       Pointer  button  one  (usually  left) is used to save text into the cut
       buffer.  Move the cursor to beginning of the text, and  then  hold  the
       button  down  while  moving  the  cursor  to  the end of the region and
       releasing the button.  The selected text is highlighted and is saved in
       the global cut buffer and made the PRIMARY selection when the button is
       released.  Normally (but see the discussion of on2Clicks, etc):

              -  Double-clicking selects by words.

              -  Triple-clicking selects by lines.

              -  Quadruple-clicking goes back to characters, etc.

       Multiple-click is determined by the time from button up to button down,
       so  you  can  change  the  selection unit in the middle of a selection.
       Logical words and lines selected by double- or triple-clicking may wrap
       across  more than one screen line if lines were wrapped by xterm itself
       rather than by the application running in the window.  If the  key/but-
       ton  bindings  specify  that  an  X selection is to be made, xterm will
       leave the selected text highlighted for as long as it is the  selection
       owner.

       Pointer  button two (usually middle) 'types' (pastes) the text from the
       PRIMARY selection, if any, otherwise from the cut buffer, inserting  it
       as keyboard input.

       Pointer  button  three  (usually  right) extends the current selection.
       (Without loss of generality, you can swap ''right'' and ''left'' every-
       where  in  the rest of this paragraph.)  If pressed while closer to the
       right edge of the selection than the  left,  it  extends/contracts  the
       right  edge  of  the selection.  If you contract the selection past the
       left edge of the selection, xterm assumes you  really  meant  the  left
       edge,  restores the original selection, then extends/contracts the left
       edge of the selection.  Extension starts in  the  selection  unit  mode
       that  the  last selection or extension was performed in; you can multi-
       ple-click to cycle through them.

       By cutting and pasting pieces of text without trailing new  lines,  you
       can  take text from several places in different windows and form a com-
       mand to the shell, for example, or  take  output  from  a  program  and
       insert  it  into  your favorite editor.  Since cut buffers are globally
       shared among different applications, you may regard each  as  a  'file'
       whose contents you know.  The terminal emulator and other text programs
       should be treating it as if it were a text  file,  i.e.,  the  text  is
       delimited by new lines.

   SCROLLING
       The  scroll  region  displays the position and amount of text currently
       showing in the window (highlighted) relative  to  the  amount  of  text
       actually saved.  As more text is saved (up to the maximum), the size of
       the highlighted area decreases.

       Clicking button one with the pointer in the  scroll  region  moves  the
       adjacent line to the top of the display window.

       Clicking  button three moves the top line of the display window down to
       the pointer position.

       Clicking button two moves the display to a position in the  saved  text
       that corresponds to the pointer's position in the scrollbar.

   TEKTRONIX POINTER
       Unlike  the VT102 window, the Tektronix window does not allow the copy-
       ing of text.  It does allow Tektronix GIN mode, and in  this  mode  the
       cursor  will  change  from  an arrow to a cross.  Pressing any key will
       send that key and the current coordinate of the cross cursor.  Pressing
       button  one,  two,  or three will return the letters 'l', 'm', and 'r',
       respectively.  If the 'shift' key is pressed when a pointer  button  is
       pressed, the corresponding upper case letter is sent.  To distinguish a
       pointer button from a key, the high bit of the character  is  set  (but
       this  is  bit is normally stripped unless the terminal mode is RAW; see
       tty(4) for details).

MENUS
       Xterm has four menus, named mainMenu, vtMenu,  fontMenu,  and  tekMenu.
       Each  menu  pops  up  under  the correct combinations of key and button
       presses.  Each menu is divided into sections, separated by a horizontal
       line.   Some  menu  entries correspond to modes that can be altered.  A
       check mark appears next to a mode that is currently active.   Selecting
       one of these modes toggles its state.  Other menu entries are commands;
       selecting one of these performs the indicated function.

       All of the menu entries correspond to X actions.  In  the  list  below,
       the menu label is shown followed by the action's name in parenthesis.

   Main Options
       The  xterm mainMenu pops up when the ''control'' key and pointer button
       one are pressed in a window.  This menu contains items  that  apply  to
       both the VT102 and Tektronix windows.  There are several sections:

       Commands for managing X events:

              Toolbar
                     Clicking on the "Toolbar" menu entry hides the toolbar if
                     it is visible, and shows it if it is not.

              Secure Keyboard (securekbd)
                     The Secure Keyboard mode is helpful when typing in  pass-
                     words or other sensitive data in an unsecure environment;
                     see SECURITY below (but read the limitations  carefully).

              Allow SendEvents (allowsends )
                     Specifies  whether or not synthetic key and button events
                     generated using the X protocol SendEvent  request  should
                     be  interpreted  or  discarded.   This corresponds to the
                     allowSendEvents resource.

              Redraw Window (redraw)
                     Forces the X display to repaint; useful in some  environ-
                     ments.

       Commands for capturing output:

              Log to File (logging)
                     Captures  text sent to the screen in a logfile, as in the
                     -l logging option.

              Print Window (print)
                     Sends the text of the current window to the program given
                     in the printerCommand resource.

              Redirect to Printer (print-redir)
                     This  sets the printerControlMode to 0 or 2.  You can use
                     this to turn the printer on as if an application had sent
                     the  appropriate control sequence.  It is also useful for
                     switching the printer off if an application turns  it  on
                     without resetting the print control mode.

       Modes for setting keyboard style:

              8-Bit Controls (8-bit-control)
                     Enabled  for VT220 emulation, this controls whether xterm
                     will send 8-bit control sequences rather than using 7-bit
                     (ASCII)  controls,  e.g.,  sending  a  byte  in the range
                     128-159 rather than the escape character  followed  by  a
                     second  byte.   Xterm  always  interprets  both 8-bit and
                     7-bit control sequences (see the document  Xterm  Control
                     Sequences).   This  corresponds  to  the  eightBitControl
                     resource.

              Backarrow Key (BS/DEL) (backarrow key)
                     Modifies the behavior of the  backarrow  key,  making  it
                     transmit  either  a backspace (8) or delete (127) charac-
                     ter.  This corresponds to the backarrowKey resource.

              Alt/NumLock Modifiers (num-lock)
                     Controls the treatment of Alt- and NumLock-key modifiers.
                     This corresponds to the numLock resource.

              Meta Sends Escape (meta-esc)
                     Controls whether Meta keys are converted into a two-char-
                     acter sequence with the character itself preceded by ESC.
                     This corresponds to the metaSendsEscape resource.

              Delete is DEL (delete-is-del)
                     Controls  whether  the  Delete  key on the editing keypad
                     should send DEL (127) or the  VT220-style  Remove  escape
                     sequence.   This corresponds to the deleteIsDEL resource.

              Old Function-Keys (oldFunctionKeys)

              HP Function-Keys (hpFunctionKeys)

              SCO Function-Keys (scoFunctionKeys)

              Sun Function-Keys (sunFunctionKeys)

              VT220 Keyboard (sunKeyboard)
                     These act as a radio-button, selecting one style for  the
                     keyboard   layout.   It  corresponds  to  more  than  one
                     resource setting: sunKeyboard, sunFunctionKeys,  scoFunc-
                     tionKeys and hpFunctionKeys ."

       Commands for process signalling:

              Send STOP Signal (suspend)

              Send CONT Signal (continue)

              Send INT Signal (interrupt)

              Send HUP Signal (hangup)

              Send TERM Signal (terminate)

              Send KILL Signal (kill)
                     These  send the SIGTSTP, SIGCONT, SIGINT, SIGHUP, SIGTERM
                     and SIGKILL signals respectively, to the process group of
                     the process running under xterm (usually the shell).  The
                     SIGCONT function is especially useful  if  the  user  has
                     accidentally typed CTRL-Z, suspending the process.

              Quit (quit)
                     Stop  processing  X  events  except  to support the -hold
                     option, and then send a SIGHUP signal to the the  process
                     group  of  the  process  running under xterm (usually the
                     shell).

   VT Options
       The vtMenu sets various modes in the VT102 emulation, and is popped  up
       when  the  ''control''  key  and  pointer button two are pressed in the
       VT102 window.

       VT102/VT220 Modes:

              Enable Scrollbar (scrollbar)
                     Enable (or disable) the scrollbar.  This  corresponds  to
                     the -sb option and the scrollBar resource.

              Enable Jump Scroll (jumpscroll)
                     Enable  (or disable) jump scrolling.  This corresponds to
                     the -j option and the jumpScroll resource.

              Enable Reverse Video (reversevideo)
                     Enable (or disable) reverse-video.  This  corresponds  to
                     the -rv option and the reverseVideo resource.

              Enable Auto Wraparound (autowrap)
                     Enable (or disable) auto-wraparound.  This corresponds to
                     the -aw option and the autoWrap resource.

              Enable Reverse Wraparound (reversewrap)
                     Enable (or disable) reverse wraparound.  This corresponds
                     to the -rw option and the reverseWrap resource.

              Enable Auto Linefeed (autolinefeed)
                     Enable (or disable) auto-linefeed.  This is the VT102 NEL
                     function, which causes the emulator to  emit  a  linefeed
                     after  each  carriage  return.  There is no corresponding
                     command-line option or resource setting.

              Enable Application Cursor Keys (appcursor)
                     Enable (or disable) application cursor keys.  This corre-
                     sponds  to  the  appcursorDefault  resource.  There is no
                     corresponding command-line option.

              Enable Application Keypad (appkeypad)
                     Enable (or disable) application keypad keys.  This corre-
                     sponds  to  the  appkeypadDefault  resource.  There is no
                     corresponding command-line option.

              Scroll to Bottom on Key Press (scrollkey)
                     Enable (or  disable)  scrolling  to  the  bottom  of  the
                     scrolling  region on a keypress.  This corresponds to the
                     -sk option and the scrollKey resource.

              Scroll to Bottom on Tty Output (scrollttyoutput)
                     Enable (or  disable)  scrolling  to  the  bottom  of  the
                     scrolling region on output to the terminal..  This corre-
                     sponds  to  the  -si  option  and   the   scrollTtyOutput
                     resource.

              Allow 80/132 Column Switching (allow132)
                     Enable (or disable) switching between 80 and 132 columns.
                     This  corresponds  to  the  -132  option  and  the   c132
                     resource.

              Select to Clipboard (selectToClipboard)
                     Tell  xterm  whether  to use the PRIMARY or CLIPBOARD for
                     SELECT tokens in the  translations  resource  which  maps
                     keyboard and mouse actions to select/paste actions.  This
                     corresponds to the selectToClipboard resource.  There  is
                     no corresponding command-line option.

              Enable Visual Bell (visualbell)
                     Enable (or disable) visible bell (i.e., flashing) instead
                     of an audible bell.  This corresponds to the  -vb  option
                     and the visualBell resource.

              Enable Pop on Bell (poponbell)
                     Enable  (or disable) raising of the window when Control-G
                     is received.  This corresponds to the -pop option and the
                     popOnBell resource.

              Enable Margin Bell (marginbell)
                     Enable  (or  disable) a bell when the user types near the
                     right margin.  This corresponds to the -mb option and the
                     marginBell resource.

              Enable Blinking Cursor (cursorblink)
                     Enable  (or  disable)  the blinking-cursor feature.  This
                     corresponds  to  the  -bc  option  and  the   cursorBlink
                     resource.  There is also an escape sequence (see the doc-
                     ument Xterm Control Sequences).  The menu entry  and  the
                     escape  sequence  states  are XOR'd: if both are enabled,
                     the cursor will not blink, if only one  is  enabled,  the
                     cursor will blink.

              Enable Alternate Screen Switching (titeInhibit)
                     Enable  (or  disable)  switching  between  the normal and
                     alternate screens.  This corresponds to  the  titeInhibit
                     resource.  There is no corresponding command-line option.

              Enable Active Icon (activeicon)
                     Enable (or disable) the active-icon feature.  This corre-
                     sponds to the -ai option and the activeIcon resource.

       VT102/VT220 Commands:

              Do Soft Reset (softreset)
                     Reset  scroll  regions.  This can be convenient when some
                     program has  left  the  scroll  regions  set  incorrectly
                     (often a problem when using VMS or TOPS-20).  This corre-
                     sponds to the VT220 DECSTR control sequence.

              Do Full Reset (hardreset)
                     The full reset entry will clear the screen, reset tabs to
                     every  eight  columns, and reset the terminal modes (such
                     as wrap and smooth scroll) to their initial  states  just
                     after  xterm  has  finished  processing  the command line
                     options.  This  corresponds  to  the  VT102  RIS  control
                     sequence,  with  a few obvious differences.  For example,
                     your session is not disconnected as a  real  VT102  would
                     do.

              Reset and Clear Saved Lines (clearsavedlines)
                     Perform a full reset, and also clear the saved lines.

       Commands for setting the current screen:

              Show Tek Window (tekshow)
                     When enabled, pops the Tektronix 4014 window up (makes it
                     visible).  When disabled, hides the Tektronix  4014  win-
                     dow.

              Switch to Tek Mode (tekmode)
                     When  enabled, pops the Tektronix 4014 window up if it is
                     not already visible, and switches  the  input  stream  to
                     that  window.   When  disabled,  hides the Tektronix 4014
                     window and switches input back to the VTxxx window.

              Hide VT Window (vthide)
                     When enabled, hides the VTxxx window, shows the Tektronix
                     4014  window  if  it was not already visible and switches
                     the input stream to that window.   When  disabled,  shows
                     the  VTxxx  window, and switches the input stream to that
                     window.

              Show Alternate Screen (altscreen)
                     When enabled, shows the alternate screen.  When disabled,
                     shows the normal screen.  Note that the normal screen may
                     have saved lines; the alternate screen does not.

   VT Fonts
       The fontMenu pops up when when the ''control'' key and  pointer  button
       three are pressed in a window.  It sets the font used in the VT102 win-
       dow, or modifies the way the font is specified or displayed.  There are
       three sections.

       The  first section allows you to select the font from a set of alterna-
       tives:

              Default (fontdefault)
                     Set the font to the default,  i.e.,  that  given  by  the
                     *VT100.font resource.

              Unreadable (font1)
                     Set  the font to that given by the *VT100.font1 resource.

              Tiny (font2)
                     Set the font to that given by the *VT100.font2  resource.

              Small (font3)
                     Set  the font to that given by the *VT100.font3 resource.

              Medium (font4)
                     Set the font to that given by the *VT100.font4  resource.

              Large (font5)
                     Set  the font to that given by the *VT100.font5 resource.

              Huge (font6)
                     Set the font to that given by the *VT100.font6  resource.

              Escape Sequence
                     This allows you to set the font last specified by the Set
                     Font escape sequence  (see  the  document  Xterm  Control
                     Sequences).

              Selection (fontsel)
                     This  allows  you  to  set the font specified the current
                     selection as a font name (if  the  PRIMARY  selection  is
                     owned).

       The second section allows you to modify the way it is displayed:

              Line-Drawing Characters (font-linedrawing)
                     When  set, tells xterm to draw its own line-drawing char-
                     acters.  Otherwise  it  relies  on  the  font  containing
                     these.  Compare to the forceBoxChars resource.

              Doublesized Characters (font-doublesize)
                     When set, xterm may ask the font server to produce scaled
                     versions of the normal font, for VT102 double-size  char-
                     acters.

       The third section allows you to modify the way it is specified:

              TrueType Fonts (render-font)
                     If  the  renderFont and corresponding resources were set,
                     this is a further control whether xterm will actually use
                     the Xft library calls to obtain a font.

              UTF-8 (utf8-mode)
                     This  controls  whether  xterm  uses  UTF-8  encoding  of
                     input/output.  It is  useful  for  temporarily  switching
                     xterm  to display text from an application which does not
                     follow the locale settings.

   TEK Options
       The tekMenu sets various modes  in  the  Tektronix  emulation,  and  is
       popped  up  when the ''control'' key and pointer button two are pressed
       in the Tektronix window.  The current font size is checked in the modes
       section of the menu.

              Large Characters (tektextlarge)

              #2 Size Characters (tektext2)

              #3 Size Characters (tektext3)

              Small Characters (tektextsmall)

       Commands:

              PAGE (tekpage)
                     Clear the Tektronix window.

              RESET (tekreset)

              COPY (tekcopy)

       Windows:

              Show VT Window (vtshow)

              Switch to VT Mode (vtmode)

              Hide Tek Window (tekhide)

SECURITY
       X  environments  differ in their security consciousness.  Most servers,
       run under xdm, are capable of using a  ''magic  cookie''  authorization
       scheme that can provide a reasonable level of security for many people.
       If your server is only using a host-based mechanism to  control  access
       to  the server (see xhost(1)), then if you enable access for a host and
       other users are also permitted to run clients on that same host, it  is
       possible  that someone can run an application which uses the basic ser-
       vices of the X protocol to snoop on your activities,  potentially  cap-
       turing  a  transcript of everything you type at the keyboard.  Any pro-
       cess which has access to your X display can manipulate it in ways  that
       you  might not anticipate, even redirecting your keyboard to itself and
       sending events to your application's windows.  This is true  even  with
       the  ''magic  cookie'' authorization scheme.  While the allowSendEvents
       provides some protection against rogue applications tampering with your
       programs, guarding against a snooper is harder.

       The  possibility of an application spying on your keystrokes is of par-
       ticular concern when you want to type in a password or other  sensitive
       data.   The best solution to this problem is to use a better authoriza-
       tion mechanism than is provided by X.  Given all of  these  caveats,  a
       simple mechanism exists for protecting keyboard input in xterm.

       The  xterm  menu  (see  MENUS  above)  contains a Secure Keyboard entry
       which, when enabled, attempts to ensure  that  all  keyboard  input  is
       directed only to xterm (using the GrabKeyboard protocol request).  When
       an application prompts you for a password (or  other  sensitive  data),
       you  can  enable  Secure Keyboard using the menu, type in the data, and
       then disable Secure Keyboard using the menu again.  This  ensures  that
       you  know  which window is accepting your keystrokes.  It cannot ensure
       that there are no processes which have access to your  X  display  that
       might be observing the keystrokes as well.

       Only  one X client at a time can grab the keyboard, so when you attempt
       to enable Secure Keyboard it may fail.  In this  case,  the  bell  will
       sound.   If the Secure Keyboard succeeds, the foreground and background
       colors will be exchanged (as if you selected the Reverse Video entry in
       the  Modes  menu);  they  will  be exchanged again when you exit secure
       mode.  If the colors do not switch, then you should be very  suspicious
       that  you  are  being spoofed.  If the application you are running dis-
       plays a prompt before asking for the password, it is  safest  to  enter
       secure mode before the prompt gets displayed, and to make sure that the
       prompt gets displayed correctly (in the new colors),  to  minimize  the
       probability of spoofing.  You can also bring up the menu again and make
       sure that a check mark appears next to the entry.

       Secure Keyboard mode will be disabled automatically if your xterm  win-
       dow  becomes  iconified  (or  otherwise unmapped), or if you start up a
       reparenting window manager (that places a title bar or other decoration
       around  the  window) while in Secure Keyboard mode.  (This is a feature
       of the X protocol not easily overcome.)  When this happens,  the  fore-
       ground  and  background  colors will be switched back and the bell will
       sound in warning.

CHARACTER CLASSES
       Clicking the left mouse button twice in rapid succession (double-click-
       ing)  causes  all  characters  of  the same class (e.g., letters, white
       space, punctuation) to be selected as a ''word''.  Since different peo-
       ple  have  different preferences for what should be selected (for exam-
       ple, should filenames be selected as a whole or only the separate  sub-
       names),  the  default  mapping can be overridden through the use of the
       charClass (class CharClass) resource.

       This resource is a series of comma-separated of range:value pairs.  The
       range is either a single number or low-high in the range of 0 to 65535,
       corresponding to the code for the character or characters  to  be  set.
       The  value  is arbitrary, although the default table uses the character
       number of the first character occurring in the set.  When not in  UTF-8
       mode, only the first 256 bytes of this table will be used.

       The default table starts as follows -

           static int charClass[256] = {
           /* NUL  SOH  STX  ETX  EOT  ENQ  ACK  BEL */

       For  example,  the string ''33:48,37:48,45-47:48,38:48'' indicates that
       the exclamation mark, percent sign, dash, period, slash, and  ampersand
       characters  should  be  treated the same way as characters and numbers.
       This is useful for cutting and pasting electronic mailing addresses and
       filenames.

ACTIONS
       It  is  possible  to  rebind  keys  (or sequences of keys) to arbitrary
       strings for input, by changing the translations resources for the vt100
       or  tek4014  widgets.   Changing  the  translations resource for events
       other than key and button events is not expected, and will cause unpre-
       dictable  behavior.   The following actions are provided for use within
       the vt100 or tek4014 translations resources:

       allow-send-events(on/off/toggle)
               This action set or toggles the allowSendEvents resource and  is
               also invoked by the allowsends entry in mainMenu.

       alt-sends-escape()
               This action toggles the state of the eightBitInput resource.

       bell([percent])
               This action rings the keyboard bell at the specified percentage
               above or below the base volume.

       clear-saved-lines()
               This action does hard-reset() (see below) and also  clears  the
               history  of  lines saved off the top of the screen.  It is also
               invoked from the clearsavedlines entry in vtMenu.   The  effect
               is identical to a hardware reset (RIS) control sequence.

       create-menu(m/v/f/t)
               This  action  creates one of the menus used by xterm, if it has
               not been previously created.  The parameter values are the menu
               names: mainMenu, vtMenu, fontMenu, tekMenu, respectively.

       dabbrev-expand()
               Expands  the  word  before cursor by searching in the preceding
               text on the screen and  in  the  scrollback  buffer  for  words
               starting  with  that  abbreviation.  Repeating dabbrev-expand()
               several times in sequence searches for an alternative expansion
               by looking farther back.  Lack of more matches is signaled by a
               beep().  Attempts to expand an empty word (i.e., when cursor is
               preceded  by  a  space)  yield successively all previous words.
               Consecutive identical expansions are ignored.  The word here is
               defined  as a sequence of non-whitespace characters.  This fea-
               ture partially emulates the behavior of 'dynamic  abbreviation'
               expansion  in  Emacs  (bound there to M-/).  Here is a resource
               setting for xterm which will do the same thing:

                   *VT100*translations:    #override \n\
                        Meta <KeyPress> /:dabbrev-expand()

       deiconify()
               Changes the window state back to normal, if it was iconified.

       delete-is-del()
               This action toggles the state of the deleteIsDEL resource.

       dired-button()
               Handles a button event (other than press and release) by  echo-
               ing  the  event's position (i.e., character line and column) in
               the following format:

                       ^X ESC G <line+' '> <col+' '>

       iconify()
               Iconifies the window.

       hard-reset()
               This action resets the scrolling region, tabs, window size, and
               cursor keys and clears the screen.  It is also invoked from the
               hardreset entry in vtMenu.

       ignore()
               This action ignores the event but checks  for  special  pointer
               position escape sequences.

       insert()
               This action inserts the character or string associated with the
               key that was pressed.

       insert-eight-bit()
               This action inserts an eight-bit (Meta) version of the  charac-
               ter  or  string associated with the key that was pressed.  This
               only applies to single-byte values.  The exact  action  depends
               on  the  value  of  the  metaSendsEscape  and the eightBitInput
               resources.  The metaSendsEscape resource is tested first.

               The term "eight-bit" is misleading: xterm checks if  the  key's
               value  is  less  than 128.  If so, xterm adds 128 to the value,
               setting its eighth bit.  Otherwise  xterm  sends  an  ESC  byte
               before  the key.  In other applications' documentation, that is
               referred to as a "meta key".

       insert-selection(sourcename [, ...])
               This action inserts the string found in the selection  or  cut-
               buffer  indicated  by  sourcename.   Sources are checked in the
               order given (case is significant) until  one  is  found.   Com-
               monly-used  selections  include:  PRIMARY, SECONDARY, and CLIP-
               BOARD.  Cut buffers are  typically  named  CUT_BUFFER0  through
               CUT_BUFFER7.

       insert-seven-bit()
               This  action  is a synonym for insert() The term "seven-bit" is
               misleading: it only implies that xterm does not try to add  128
               to the key's value as in insert-eight-bit().

       interpret(control-sequence)
               Interpret  the  given  control  sequence locally, i.e., without
               passing it to the host.  This works by  inserting  the  control
               sequence  at  the front of the input buffer.  Use "\" to escape
               octal digits in the string.  Xt does not allow  you  to  put  a
               null character (i.e., "\000") in the string.

       keymap(name)
               This  action  dynamically defines a new translation table whose
               resource name is name with the suffix Keymap (case is  signifi-
               cant).   The name None restores the original translation table.

       larger-vt-font()
               Set the font to the next larger one, based on the  font  dimen-
               sions.  See also set-vt-font().

       load-vt-fonts(name[,class])
               Load fontnames from the given subresource name and class.  That
               is, load the "*VT100.name.font", resource as "*VT100.font" etc.
               If no name is given, the original set of fontnames is restored.

               Unlike set-vt-font(), this does  not  affect  the  escape-  and
               select-fonts, since those are not based on resource values.  It
               does affect the fonts loosely organized under  the  ''Default''
               menu entry: font, boldFont, wideFont and wideBoldFont.

       maximize()

               printer off if you happen to change your mind after deciding to
               print random binary files on the terminal.

       quit()  This action sends a SIGHUP to the subprogram and exits.  It  is
               also invoked by the quit entry in mainMenu.

               had  previously scrolled off the top of the screen is now visi-
               ble.

               The count argument indicates the number of units (which may  be
               page, halfpage, pixel, or line) by which to scroll.

               An  adjustment can be specified for these values by appending a
               "+" or "-" sign followed by a number, e.g., page-2 to specify 2
               lines less than a page.

               If  the  third  parameter mouse is given, the action is ignored
               when mouse reporting is enabled.

       scroll-forw(count [,units [,mouse] ])

               pace or non-alphanumeric characters.  If  the  string  argument
               begins  with  the characters ''0x'', it is interpreted as a hex
               character constant.

       tek-copy()
               This action copies the escape codes used to generate  the  cur-
               rent  window contents to a file in the current directory begin-
               ning with the name COPY.  It is also invoked from  the  tekcopy
               entry in tekMenu.

               the tekreset entry in tekMenu.

       vi-button()
               Handles  a button event (other than press and release) by echo-
               ing a control sequence computed from the event's line number in
               the screen relative to the current line:

                       ESC ^P
               or
                       ESC ^N

               according  to whether the event is before, or after the current
               line, respectively.  The ^N (or ^P) is repeated once  for  each
               line that the event differs from the current line.  The control
               sequence is omitted altogether if the button event  is  on  the
               current line.

       visual-bell()
               This action flashes the window quickly.

       The Tektronix window also has the following action:

       gin-press(l/L/m/M/r/R)
               This action sends the indicated graphics input code.

       The default bindings in the VT102 window use the SELECT token, which is
       set by the selectToClipboard resource:

       Here is an example which uses shifted select/paste to copy to the clip-
       board,  and  unshifted select/paste for the primary selection.  In each
       case, a (different) cut buffer is  also  a  target  or  source  of  the
       select/paste  operation.  It is important to remember however, that cut
       buffers store data in ISO-8859-1 encoding, while selections  can  store
       data  in  a  variety  of  formats  and encodings.  While xterm owns the
       selection, it highlights it.  When it loses the selection,  it  removes
       the  corresponding  highlight.  But you can still paste from the corre-
       sponding cut buffer.

           *VT100*translations:    #override \n\
               ~Shift~Ctrl<Btn2Up>: insert-selection(PRIMARY, CUT_BUFFER0) \n\
               Shift~Ctrl<Btn2Up>:  insert-selection(CLIPBOARD, CUT_BUFFER1) \n\
               ~Shift<BtnUp>:       select-end(PRIMARY, CUT_BUFFER0) \n\
               Shift<BtnUp>:        select-end(CLIPBOARD, CUT_BUFFER1)

       Below is a sample how of the keymap() action is  used  to  add  special
       keys for entering commonly-typed works:

           *VT100.Translations: #override <Key>F13: keymap(dbx)
           *VT100.dbxKeymap.translations: \
                <Key>F14: keymap(None) \n\
                <Key>F17: string("next") string(0x0d) \n\
                <Key>F18: string("step") string(0x0d) \n\
                <Key>F19: string("continue") string(0x0d) \n\
                <Key>F20: string("print ") insert-selection(PRIMARY, CUT_BUFFER0)

CONTROL SEQUENCES AND KEYBOARD
       The  Xterm Control Sequences document lists the control sequences which
       an application can send xterm to make it  perform  various  operations.
       Most  of these operations are standardized, from either the DEC or Tek-
       tronix terminals, or from more widely used standards such as ISO  6429.

ENVIRONMENT
       Xterm sets several environment variables:

       DISPLAY
            is  the  display name, pointing to the X server (see DISPLAY NAMES
            in X(el5_4.1-root-mockbuild/usr/share/man/xterm.1)).

       TERM is set according to the termcap (or terminfo) entry  which  it  is
            using as a reference.

       WINDOWID
            is set to the X window id number of the xterm window.

       XTERM_SHELL
            is  set  to the pathname of the program which is invoked.  Usually
            that is a shell program, e.g., /bin/sh.  Since it is not necessar-
            ily a shell program however, it is distinct from ''SHELL''.

       XTERM_VERSION
            is  set  to  the string displayed by the -version option.  That is
            normally an identifier for the X Window libraries  used  to  build
            xterm, followed by xterm's patch number in parenthesis.  The patch
            number is  also  part  of  the  response  to  a  Secondary  Device
            Attributes (DA) control sequence (see Xterm Control Sequences).

       Depending  on your system configuration, xterm may also set the follow-
       ing:

       COLUMNS
            the width of the xterm in characters (cf: "stty columns").

       HOME when xterm is configured to update utmp.

       LINES
            the height of the xterm in characters (cf: "stty rows").

       LOGNAME
            when xterm is configured to update utmp.

       SHELL
            when xterm is configured to update utmp.  It is also  set  if  you
            provide the shell name as the optional parameter.

       TERMCAP
            the  contents  of  the  termcap entry corresponding to $TERM, with
            lines and columns values substituted for the  actual  size  window
            you have created.

       TERMINFO
            may  be defined to a nonstandard location in the configure script.

FILES
       The actual pathnames given may differ on your system.

       /etc/utmp
            the system logfile, which records user logins.

       /etc/wtmp
            the system logfile, which records user logins and logouts.

       /usr/share/X11/app-defaults/XTerm
            the xterm default application resources.

       /usr/share/X11/app-defaults/XTerm-color
            the xterm color application resources.  If your  display  supports
            color, use this
                      *customization: -color
            in  your  .Xdefaults  file to automatically use this resource file
            rather than /usr/share/X11/app-defaults/XTerm.  If you do  not  do
            this,  xterm  uses  its  compiled-in default resource settings for
            colors.

ERROR MESSAGES
       Most of the fatal error messages from xterm use the following format:
              xterm: Error XXX, errno YYY: ZZZ
       The XXX codes (which are used by xterm as  its  exit-code)  are  listed
       below, with a brief explanation.

       1    is  used  for  miscellaneous errors, usually accompanied by a spe-
            cific message,

BUGS
       Large pastes do not work on some systems.  This is not a bug in  xterm;
       it  is  a  bug  in  the pseudo terminal driver of those systems.  xterm
       feeds large pastes to the pty only as fast as the pty will accept data,
       but  some  pty  drivers do not return enough information to know if the
       write has succeeded.

       Many of the options are not resettable after xterm starts.

       This program still needs to be rewritten.  It should be split into very
       modular  sections, with the various emulators being completely separate
       widgets that do not know about each other.  Ideally, you'd like  to  be
       able  to  pick and choose emulator widgets and stick them into a single
       control widget.

       There needs to be a dialog box to allow entry  of  the  Tek  COPY  file
       name.
