I've found a problem with the syntax highlighting in the LaTeX bundle. I use the Cobalt theme, and normally the argument of a citation command such as `\citeauthor` appears in purple. However, I have the following line in a document I am writing:
\section{\citeauthor{kager:1999}'s analysis}
The arguments to section commands normally show up gold-colored for me, and "analysis" appropriately does so here. However, the `kager:1999` part also does, which I believe is incorrect since it is not part of the actual section title but rather a bibliography keyword and thus should be purple.
Not a huge problem, but I wanted to point it out. I would fix it if I had time to learn TextMate's grammar system -- as I said, I'm currently writing a paper. :-)
