   Based on feedback from Andreas & Hannu, I've made some tentative changes
   to the ilisp fsf key bindings . . .

   Let me know if these bindings look better than the previous ones. If I
   don't hear any complaints, I'll upload these mods to cvs in the next day
   or two.

   P.S. - Here is a listing of the revised C-c prefix bindings:

   . . .

   Buffer/Edit bindings (C-c C-g):
   C-c C-g C-l	load-file-lisp
   C-c C-g TAB	select-ilisp
   C-c C-g C-c	call-defun-lisp
   C-c C-g C-a	switch-to-lisp
   C-c C-g C-g	clear-changes-lisp
   C-c C-g C-@	list-changes-lisp
   C-c C-g SPC	mark-change-lisp
   C-c C-g C-d	default-directory-lisp
   C-c C-g C-p	set-package-lisp
   C-c C-g C-n	next-caller-lisp
   C-c C-g C-e	edit-callers-lisp
   C-c C-g C-r	replace-lisp
   C-c C-g C-s	search-lisp
   C-c C-g C-u	find-unbalanced-lisp
   C-c C-g C-\	comment-region-lisp
   C-c C-g C-]	close-all-lisp

   . . .

Sorry for not noticing this sooner (I was away last weekend), but using
C-g as a second character means that if you type C-c and then change
your mind, you need to type C-g twice to cancel the prefix.  (If the C-g
is not part of a valid key sequence, of course, you only need to type it
once.)  It's a minor inconvenience, but it would be inconsistent with
other modes, and that can be confusing.  Since there is no mnemonic
value to C-g here, how about choosing another character instead?  C-e
for "extra"?  C-r for "random"?  Both of these are suitable, because
they are typed with the same hand as C-c (so you don't have to change
control keys), but C-r has an edge, because it is typed with a different
finger.

   Which brings up another point:  If you are touch-typing a sequence of
control characters on a standard keyboard, it matters which hand(s) you
need.  Typing "C-c C-g p" is actually easier than "C-c C-g C-p" because
you touch-type "C-g" using the right control key, and "C-p" using the
left control key.  So there doesn't seem to be a general metric for
what's easier to type; it depends on how you type it.  But other than
that, I'm afraid I don't have time now to explore the implications . . .
