-display, this ``minimizes'' (or ``iconifies'') the selected Emacs
-frame. On a text terminal, this suspends the Emacs process.
-
- After minimizing or suspending Emacs, you can return to it and
-continue editing wherever you left off. The way to do this depends on
-the window system or shell. In most common shells, you can resume
-Emacs after suspending it with the shell command @command{%emacs}.
-
-@vindex cannot-suspend
- On very old systems that don't support suspending programs,
-@kbd{C-z} starts an inferior shell that communicates directly with the
-terminal, and Emacs waits until you exit the subshell. (The way to
-exit the subshell is usually @kbd{C-d} or @command{exit}.) On these
-systems, you can only get back to the shell from which Emacs was run
-(to log out, for example) when you kill Emacs. Suspending can also
-fail if you run Emacs under a shell that doesn't support suspending
-jobs, even if the system itself does support it. In this case, you
-can set the variable @code{cannot-suspend} to a non-@code{nil} value
-to force @kbd{C-z} to start an inferior shell.
-
- Text-only terminals usually listen for certain special characters
-whose meaning is to kill or suspend the program you are running.
-@b{This terminal feature is turned off while you are in Emacs.} The
-meanings of @kbd{C-z} and @kbd{C-x C-c} as keys in Emacs were inspired
-by the use of @kbd{C-z} and @kbd{C-c} on several operating 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}).
