[#bugs]Directions while aiming not perfect for numpad 1, 3, 7, 9

After pressing F while holding a ranged weapon puts the player into aim mode. Numpad 2, 4, 6, 8 can be held down to repeat the key. Numpad 7 and 9 will move the cursor one tile but will not repeat the key. Numpad 1 and 3 does nothing. It would be nice to be able to repeat the key with numpad 1, 3, 7 and 9 since I prefer the unlocked aim most of the time instead of the locked one.
