Yeah, but just because it is enabled doesn't mean it is used. I don't know why it is enabled if it isn't used, perhaps someone else can answer that. > Now that I have understood how things work, I doubt > that it would be beneficial to use Font Lock Mode in > Help buffers, because the text could be mixed (for > example: Emacs Lisp code and regular text). That is not a problem and that happens all the time. The regexps are so advanced. This sentence - describe-key is an interactive compiled Lisp function in `help.el' - can be picked apart with only one regexp, and with groups every single word can be highlighted in a different color, and none of that that appears anywhere else would get that color. I'll do an example some other time and show you. But if you don't want it, I still want it :) -- underground experts united http://user.it.uu.se/~embe8573
