Microsoft Natural Keyboard (1994)Purpose of Menu Key
The ▤ Menu key, also known as Apps key, is meant to be a application-specific context menu key.
In folder viewer (File Explorer), after you selected a item, you can press ▤ Menu r to rename, ▤ Menu d to delete, ▤ Menu p to show info/properties, etc.
In web browsers, after you made a text selection, press ▤ Menu c to copy, and ▤ Menu p to paste. Also works in terminal and most other apps.
Menu Key Alternative: Shift+F10
Pressing Shift+F10 is the same as menu key in most applications.
Difference Between Menu Key vs Mouse Right Button
The ▤ Menu key's function is similar to mouse's right button.
Note: press the ▤ Menu key is not equivalent to pressing the right mouse button. For example, in a browser, pressing right mouse button on a link pops up a context menu for that link. But press ▤ Menu doesn't show the same context menu. You need first to put focus on the link (by pressing Tab), then press ▤ Menu.
