+As well as the primary and secondary selection types, X supports a
+@dfn{clipboard} selection type which is used by some applications,
+particularly under OpenWindows and Gnome.
+
+The command @kbd{M-x menu-bar-enable-clipboard} makes the @code{Cut},
+@code{Paste} and @code{Copy} menu items, as well as the keys of the same
+names, all use the clipboard.
+ 
+You can customize the option @code{x-select-enable-clipboard} to make
+the Emacs yank functions consult the clipboard before the primary
+selection, and to make the kill functions to store in the clipboard as
+well as the primary selection.  Otherwise they do not access the
+clipboard at all.  Using the clipboard is the default on MS-Windows,
+unlike most systems.
