@kindex C-z @r{(X windows)}
@findex iconify-or-deiconify-frame
Iconify the selected Emacs frame (@code{iconify-or-deiconify-frame}).
+When typed on an Emacs frame's icon, deiconify instead.
+
The normal meaning of @kbd{C-z}, to suspend Emacs, is not useful under
a graphical display that allows multiple applications to operate
simultaneously in their own windows, so Emacs gives @kbd{C-z} a
different binding in that case.
-If you type this command on an Emacs frame's icon, it deiconifies the frame.
