Re: How to determine what face is associated with a bit of text?

I have a more general facility I call introspector, which pops up a tooltip describing practically anything you could want to know about buffer point, and is bound to a keystroke (by default C-h =). Extension to a mouse binding like Jeff's is trivial, just bind `introspect-cursor-position' instead of d-f-a-m-p in the above. (Extensions like a hovering tooltip that follows mouse are conceivable but not high priority unless somebody asks for them with a plausible use case.) It's packaged as an XEmacs package, just drop it in your system site-packages or in ~/.xemacs/xemacs-packages or ~/.xemacs/site-packages, and add `(require 'introspector)' to your init file. (This last requirement will become unnecessary in the future, but to create a default keybinding is invasive.) http://turnbull.sk.tsukuba.ac.jp/Tools/XEmacs/introspector-0.80-pkg.tar.gz
