menu.sticky()
m.sticky(true | false | ())
Displays the menu permanently on the screen until the user
clicks the border. After calling "sticky()", the menu gets a red border.
Like all functions of this kind, the method can be called
in three ways: without a parameter, in which case it returns the
actual status as a boolean, or with one parameter:
true or false, in which case it sets the status
Toggling can be done by
m.sticky ( ! m.sticky() )
