Re: Opening Up More Keymaps Re: Standardizing more key bindings?

[Alfred M. Szmidt]

   I don't have a computer at hand to test, but I wouldn't be too
   surprised if sending SIGINT to an emacs process called
   save-buffers-kill-emacs.

SIGINT to Emacs calls keyboard-quit.

       In any case, C-z can display a message guiding the user to the
       proper key sequence. And one could argue that C-c could show
       such a message too(without breaking anything).

    C-c doesn't interrupt Emacs; so having it show a message would be
    missleading to the user.

   I don't understand. What would be misleading in a message "To quit
   emacs, type C-x C-c"?

Why should that be shown for a key that is not only unrelated to C-x
C-c but also used for an entierly different purpose?  The issue with
C-z is that one is modifying its behaviour slightly from what users
already expect, i.e. suspending Emacs.  

Showing a message that C-z no longer suspends Emacs, but if you press
z or C-z again it will do that is being helpful.  In ten years time,
maybe that message can be removed.
