Display each key that is typed in a corner of the screen

[MrTucks]

Description of the new feature / enhancement

Every time any key or key combination is pressed, the key (or key combination) should be shown in a little semi-transparent window in one corner of the screen. It should fade away after a configured amount of time.

Scenario when this would be used?

This would be very helpful when showing someone something in a screen share video call. Or when recording tutorials. For example, explaining a user how to use a specific software. Then the other user would instantly see which keys I'm pressing.

This would work great together with Mouse Higlighter. Mouse Higlighter makes it obvious when I'm clicking something. My feature would make it obvious which keys I'm pressing.
