The User Icon is used to construct custom-built menu bars for the users
of your database. Constructing a custom menu is as easy as clicking and
dragging the appropriate menu command or View, from a list of available
items, into the Menu that you've named. To add a menu to the menubar,
just click in the menubar and type in a name. You can also add
command-key equivalents by dragging a key from the keyboard (at the
bottom of the User dialogue) into the menubar next to a menu item.
