Does non-numlocked 5 send keycodes?

Question

On my laptop, on the numeric keypad, all the other numeric keys send keycodes (Up, Down, Left, Right, Home, End, Pg Up, Pg Dn, Del, Ins) when num lock is disabled, apart from number 5 in the middle.

Does it send any code at all, or is it blocked by the keyboard's logic? (like Fn)

Answer 1

Yes.

It sends the keycode 101 (i.e. number 5) when the num lock is on.

It sends the keycode 12 (i.e. Clear) when num lock is off.
