The usual way to invoke Emacs is with the shell command @command{emacs}.
Emacs clears the screen and then displays an initial help message and
as soon as you direct your keyboard input to the Emacs frame.
@vindex initial-major-mode
- When Emacs starts up, it makes a buffer named @samp{*scratch*}.
+ When Emacs starts up, it creates a buffer named @samp{*scratch*}.
That's the buffer you start out in. The @samp{*scratch*} buffer uses Lisp
Interaction mode; you can use it to type Lisp expressions and evaluate
them, or you can ignore that capability and simply doodle. (You can
log out. @xref{Files}, for more information on visiting more than one
file.
+ If you want to edit a file from another program and already have
+Emacs running, you can use the @command{emacsclient} program to open a
+file in the already running Emacs. @xref{Emacs Server}, for more
+information on editing files with Emacs from other programs.

dedicated X windows, @kbd{C-z} has a different meaning. Suspending an

@findex save-buffers-kill-emacs
- To kill Emacs, type @kbd{C-x C-c} (@code{save-buffers-kill-emacs}). A
-two-character key is used for this to make it harder to type. This
-command first offers to save any modified file-visiting buffers. If you
-do not save them all, it asks for reconfirmation with @kbd{yes} before

+@vindex confirm-kill-emacs
+ If the value of the variable @code{confirm-kill-emacs} is
+non-@code{nil}, @kbd{C-x C-c} assumes that its value is a predicate
+function, and calls that function. If the result is non-@code{nil}, the
+session is killed, otherwise Emacs continues to run. One convenient
+function to use as the value of @code{confirm-kill-emacs} is the
+function @code{yes-or-no-p}. The default value of

The operating system usually listens for certain special characters
systems as the characters for stopping or killing a program, but that is
their only relationship with the operating system. You can customize
these keys to run any commands of your choice (@pxref{Keymaps}).
