@ -512,21 +512,24 @@ editing and get rid of Emacs. The command to do this is C-x C-c.
(Don't worry; it offers to save each changed file before it kills the
Emacs.)
C-z is the usual way to exit Emacs, because it is always better not to
kill the Emacs if you are going to do any more editing. On systems
which allow it, C-z exits from Emacs to the shell but does not destroy
the Emacs; if you use the C shell, you can resume Emacs with the `fg'
command (or, more generally, with `%emacs', which works even if your
most recent job was some other). On systems where suspending is not
possible, C-z creates a subshell running under Emacs to give you the
chance to run other programs and return to Emacs afterward, but it
does not truly "exit" from Emacs. In this case, the shell command
`exit' is the usual way to get back to Emacs from the subshell.
C-z is the command to exit Emacs *temporarily*--so that you can go
back to the same Emacs session afterward.
You would use C-x C-c if you were about to log out. You would
also use it to exit an Emacs invoked under mail handling programs
and other random utilities, since they may not believe you have
really finished using the Emacs if it continues to exist.

The time to use C-x C-c is when you are about to log out. It's also
the right thing to use to exit an Emacs invoked under mail handling
programs and other random utilities, since they may not know how to
cope with suspension of Emacs. On other occasions, use C-z, and
resume the Emacs when you have more editing to do.
There are many C-x commands. The ones you know are:
