I have a keyboard with an Apple/Mac layout (Option and Command instead of Alt and Windows keys), but I can't get its number keypad to work. I was able to figure out that the number keys are being used as a directional pad (4 as left, 6 as right, etc.) I found some advice online to press fn+F6 twice to change the numpad's behavior but it doesn't do anything.
Mac numpad keypad works as directional pad
