There is a nice feature that other DVI viewers have, this is inverse search.

inverse-search allows the user point-and-click in a special part of the text
and give a singal to an editor to load the file in such line/page.

Quite useful when a LaTeX file is being editing.

xdvi has support for inverse-search which es explained (from the user point of
view) in http://xdvi.sourceforge.net/inverse-search.html

This can be supported only if the source file uses the package srcltx
(http://tug.ctan.org/info?id=srcltx) which provide a \special insertion
into the DVI file to allow to jump into TeX source file.
