I came across this post while I was trying to figure out what is syntax
spec in `font-latex-add-keywords'. I also did search of that function as
well as "syntax" in the AUCTeX manual with no avail.

`font-latex-add-keywords' is not documented but is extensively used in
style files. It seems `font-latex-user-keyword-classes' and
`font-latex-built-in-keyword-classes' partially explain what syntax spec
is. But in some style files such as beamer.el, "<" is also used. Does
that mean one can supply any char as syntax spec?

     (font-latex-add-keywords '(("frametitle" "<[{")) 'slide-title)

I am new to AUCTeX although I am trying to be fairly familiar with it so
that I can easily create styles for my LaTeX editting.

Thanks again for making AUCTeX better and better.

Best wishes,
