# The first three items of each tupel pertain to the menu bar. All
# three are None if the item is not to appeat in a menu. Otherwise,
# the first item is the menu name (in lowercase), the second item is
# the menu item label; the third item is the keyboard shortcut to be
# listed in the menu, if any. Menu items are added in the order of
# their occurrence in this table. An item of the form
# ("menu", None, None) can be used to insert a separator in the menu.
#
# The fourth item, if present is the virtual event; each of the
# remaining items is an actual key binding for the event. (Thus,
# items[3:] conveniently forms an argument list for event_add().)
