I am using AucTeX to write LaTeX and I have fontification enabled. The highlighting of marcos works but while macros like \begin are highlighted using font-lock-keyword-face all math macros (\sum, \leq to mention a few) are highlighed using font-lock-sedate-face that is reserved for ``unknown'' macros.
On the other hand AucTeX clearly has some knowledge of all these marcos since Tex-insert-macro lists many of them among possible completions. Math macros are also defined in LaTeX-math-default in latex.el.
It seems that font-latex.el does not use this information. Is there a ``best practice'' to make font-latex learn all these keywords and fontify them appropriately?
