It can be used when the right-mouse button is not present on a mouse. The key's primary function is to launch a context menu with the keyboard rather than with the usual right-mouse button. While the Windows key is present on the vast majority of keyboards intended for use with the Windows operating system, the menu key is frequently omitted in the interest of space, particularly on portable and laptop keyboards. Its symbol is usually a small icon depicting a pointer hovering above a menu, and it is typically found on the right side of the keyboard between the right Windows logo key and the right control key (or between the right alt key and the right control key). In computing, the menu key or application key ( ≣ Menu) is a key found on Microsoft Windows-oriented computer keyboards, introduced at the same time as the Windows logo key.
