However, it *does* include a fairly complete discussion of Emacs' regexps. So if you already have both that book and the built-in Emacs manual, what further documentation do you want? If you don't find them in the Emacs chapter of Friedl's book or the manual, they don't exist _in Emacs_. But maybe, your first post notwithstanding, you aren't really asking for new documentation, but in fact new features to be added to the regexps available in Emacs? That's another issue entirely, as other posters have commented on. Tyler
