The key’s primary function is to launch a Context Menu with the keyboard rather than with the usual Right-Mouse Button. It can be used when the Right-Mouse Button is not present on a mouse.

Some Windows public terminals do not have a Menu Key on their keyboard in order to prevent users from right clicking; however, in many Windows applications, a similar functionality can be invoked with the Shift + F10 keyboard shortcut, or sometimes Ctrl + Shift + F10.

Some laptop computers include a menu function on the Fn Key (usually operated by pressing Shift + Fn), however, this generally invokes functions built into the vendor’s software and is not the same as the key described above. For example, the Logitech Illuminated Keyboard has an Fn Key where the Menu Key is usually found, pressing it together with the Print Screen Key (above Home) produces the Menu Key function.

Programmers using the Windows API can intercept this key by looking for a WM_KEYDOWN message with wParam VK_APPS (defined as 0x5D in winuser.h). It has the key code 117 (0x75).
