 MacVim has a special way of binding keys to menu items that differs from other
 Vim GUI ports.  A menu binding is called a "key equivalent" in Mac OS X
-terminology.  The ":menukeyequiv" command is used to set the key equivalent of

 	:menukeyequiv File.New\ Tab <D-t>
 This sets the key equivalent of the "New Tab" menu item under the "File" menu
 to Cmd+t.
 
-Note 1: A key equivalent should always contain the Cmd key modifier flag!
-Note 2: Key equivalents take precedence over normal mappings made with ":map".

 selectors.  To support this, MacVim introduces the ":action" command.  This
 command takes the name of an action message as its only parameter.  (An action
