in reply to Learning Emacs

Er, join-with-coma? I think you mean join-with-comma. But note that if you know some Emacs Lisp, you can do much more powerful stuff; it's a programming language in itself. If you have CPerl mode (comes with XEmacs), then under the CPerl menu, or from the extended-command line (not the extended command-line!), you can perldoc modules, functions, and FAQs and have the documentation displayed in a separate buffer in manual page mode. If you're running under X with a 104-key keyboard you get menu eq M-x (at least under XEmacs), and by reconfiguring X you can reassign the physical modifier keys to different logical modifier keys; you can really get some interesting chords then -- think having to use both hands (and possibly your head, if you bind the big modifier chord plus a mouse button). Also, sequences of keys can be bound.

And of course you can extend, and extend, and extend. Write your own modes and other functions if you don't like the ones that exist; write full applications if they work well in Emacs.

This is probably going to start a holy war, but...

All Hail XEmacs!
