Menus,
like other controls, have properties and events,
which can be accessed through the Properties
window.

press the Enter
key, the menu item name is added to the menu.

(&) before

example,
to create the File menu item with the letter underlined, type &File.
•To
display

other shortcut keys (e.g., F9) for
menu items, set the ShortcutKeys
property
