+  Conversely, Emacs can exclude all commands except those that are
+particularly relevant to the current buffer.  The @kbd{M-S-x} (that's
+``meta shift x'') command works just like @kbd{M-x}, but instead of
+listing all (or most) of the commands Emacs knows about, it will only
+list the commands that have been marked as ``belonging'' to the
+current major mode, or any enabled minor modes.

   To cancel the @kbd{M-x} and not run a command, type @kbd{C-g} instead
 of entering the command name.  This takes you back to command level.
