-  When using X Windows, you can request a more powerful alternative kind
-of automatic parenthesis matching by enabling Show Paren mode.  This
-mode turns off the usual kind of matching parenthesis display and
-instead uses highlighting to show what matches.  Whenever point is after
-a close parenthesis, the close parenthesis and its matching open
-parenthesis are both highlighted; otherwise, if point is before an open
-parenthesis, the matching close parenthesis is highlighted.  (There is
-no need to highlight the open parenthesis after point because the cursor
-appears on top of that character.)  Use the command @kbd{M-x
-show-paren-mode} to enable or disable this mode.
