Questions tagged [num-lock]

Use this tag for all topics relating to the Num-Lock functionality of a keyboard or its Num-Lock LED.

The Num-Lock(Number-Lock) is a functionality of keyboards to toggle the mapping of the so-called Number Block. It is usually realized with a Num-Lock-Key and changes between either a Cursor Block(Num-Lock off) or a Number Block(Num-Lock on). The respective LED on the keyboard usually indicates the state of this function, but can be reprogrammed for any purpose via the PS/2 keyboard controller.
