Menu key
In computing, the menu key (≣ Menu), or application key, is a key with the primary function to launch a context menu with the keyboard rather than with the usual right-mouse button. It was previously found on Microsoft Windows-oriented computer keyboards and was introduced in 1994, at the same time as the Windows logo key. The menu key was sometimes omitted on smaller keyboards.
In 2024, Microsoft announced that the button would be replaced with a Microsoft Copilot key on computers promoted as "AI PCs".
In October 2024, Apple added the "Contextual Menu key" to its USB-C Magic Keyboard with Touch ID and Numeric Keypad models.
