Inserting Line Breaks into TracNav Wiki Pages

Unfortunately our wiki appears to not support inserting a line break, but only new paragraphs.

The way to do it is to make whatever text needs to have a line break between it be inside an HTML environment, e.g.

{{{
#!html
Thing on first line<br>
Thing on second line.
}}}

Note that attempting to just use a <br> on its own inside the HTML environment will result in a very large space between the two lines.
