Keys located on an extended keyboard number pad area are indicated with (pad).

NOTE: There are a few gaps, so there may be more keys as not every keyboard has been tested.
NOTES:

(break) is included as per original BBC Micro keyboard, but will not be found on most modern keyboards.

M adjust, M menu and M select are planned for mouse buttons.
