Event for VI.

Generated when the user opens a menu using the mouse or keyboard shortcut, for example, <Alt-F> to open the File menu. Also generated when the user presses shortcut keys to activate a menu item, for example, <Ctrl-C> to copy text. You can generate this event using any menu shortcut key. However, the movement and editing keys, such as Insert, Delete, Home, End, Page Up, Page Down, and the arrow keys do not generate this event.

The shortcut key does not have to exist in the menu in order to generate this event. That is, all <F> keys and any <Ctrl-n> key generates the event.

LabVIEW generates this event regardless of whether the menu item being selected with the shortcut key is disabled or enabled.

Note  This event does not return which menu on the menu bar the user opens.
