I will look at it.

Thanks, updated.

Should we update that entry to:

    ("savebox" "|{\\|[([{")

I always had the impression that syntactic fontification caters for the
arguments, not for the macro itself.  Here a small test.  Save the
attached verb-test.el where AUCTeX can find it and open a .tex file like
this:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\usepackage{verb-test}

\begin{document}

\VerbTest{foo}
\VerbTest*{foo}

\end{document}

%%% Local Variables:
%%% mode: latex
%%% TeX-master: t
%%% End:
--8<---------------cut here---------------end--------------->8---

Now uncomment the `font-latex-add-keywords' form, save the library and
hit 'C-c C-n' in your .tex file again.

For me, \VerbTest and \VerbTest* didn't get any fontification in the
first run, only their arguments.

Best, Arash
