[AUCTeX] Highlighting user-defined macros

[sven . bretfeld]

Hello list

Can anybody show me how I can define highlighting rules for my own
LateX macros in my .emacs. I hate this customize-group thing, since I
don't understand it anyway (I've tried it for an hour now).

For example, I have two self-defined functions I want to highlight in
.tex-files:

\mybox{text}
\agendum{text1}{text2}

How can I, for example, give "text" in the mybox-argument a red color,
and the "text1" of \agendum a red color and "text2" a yellow
background?

Maybe somebody can sent me a coding example from his/her own .emacs. I
will find out the rest.

Thank you for help
Sven
