- "Toggle CUA key-binding mode.
-When enabled, using shifted movement keys will activate the
-region (and highlight the region using `transient-mark-mode'),
-and typed text replaces the active selection.
-
-Also when enabled, you can use C-z, C-x, C-c, and C-v to undo,
-cut, copy, and paste in addition to the normal Emacs bindings.
-The C-x and C-c keys only do cut and copy when the region is
-active, so in most cases, they do not conflict with the normal
-function of these prefix keys.

+With a prefix argument ARG, enable CUA mode if ARG is positive,
+and disable it otherwise. If called from Lisp, enable the mode
+if ARG is omitted or nil.

+CUA mode is a global minor mode. When enabled, typed text
