The usual way to invoke Emacs is to simply type emacs at
the shell prompt (on VAX, see XVMS). If you
are running X-Windows, Emacs will also usually be listed in the
`Programs
' menu. Until the new Emacs Version 19 becomes default, the
only way to access it is by typing emacs-19 at the prompt or by
adding it to your X-Windows initialization files (see Customizing).
There are two ways of exiting Emacs---suspending Emacs
and killing Emacs. Suspending means stopping Emacs
temporarily and returning control to the shell (same as iconising the
Emacs window), allowing you to return later and resume editing on the
same job. Killing Emacs means exiting from the session
entirely---invoking Emacs again will start a new editing session. To
suspend Emacs, type CTL-z (or iconize the window with the
mouse). To kill Emacs, type CTL-x CTL-c (exit option also
available under `File
' menu in Emacs-19).
