Menus
*****

VM uses Emacs' menubar and popup menus when they are available to give
you access to more of VM's commands.  By default VM puts a context
sensitive popup menu on mouse button 3 (usually the rightmost mouse
button).  If you don't want this menu, set the variable
`vm-popup-menu-on-mouse-3' to nil.

If you set `vm-use-menus' to nil, VM will not generate a menubar for
VM folder buffers and VM won't use popup menus either.  If you set
`vm-use-menus' to `1', VM will add a single `VM' entry to the existing
menubar instead of using the whole menubar for its purposes.  That
single entry will have all the VM command submenus under it.

To make VM use the whole menubar, you must set variable `vm-use-menus'
to a list of symbols.  The symbols and the order in which they are
listed determine which menus will be in the menubar and how they are
ordered.  Valid symbol values are:
`dispose'
     This is menu of commands that are commonly used to dispose of a
     message.  E.g. reply, print, save, delete.
`emacs'
     This is actually a menu button that causes the menubar to change
     to the global Emacs menubar.  On that menubar you will find a VM
     button that will return you to the VM menubar.
`folder'
     This is a menu of folder related commands.  You can visit a
     folder, save a folder, quit a folder and so on.
`help'
     This is a menu of commands that provide information for you if
     you don't know what to do next.
`label'
     This is a menu of commands that let you add and remove message
     labels from messages.
`mark'
     This is a menu of commands that you can use to mark and unmark
     messages based on various criteria.  See Message Marks.
`motion'
     This is a menu of commands to move around inside messages and
     inside folders.
`send'
     This is a menu of commands you use to compose and send messages.
`sort'
     This is a menu of commands to sort a folder by various criteria.
`undo'
     This is a menu button that invokes the `vm-undo' command.
`virtual'
     This is a menu of commands that let you visit and create virtual
     folders.
`nil'
     If nil appears in the list, it should appear exactly once.  All
     menus after nil in the list will be displayed flushright in
     menubar.
