I have an extended keyboard as in the image below

enter image description here

When connecting to a Windows machine, which key is Num Lock?

For future reference, the key on this UK keyboard does not say Clear, it has an image of a horizontal rectangle with an X through it but it is the same key and provides the same functionality in OS X.

Under Boot Camp, it's the Clear ⌧ button, according to Apple's documentation.

That makes some sense, at least, because that key is where Num Lock normally lives on other keyboards.

(Note: I don't have the same keyboard to test with, but I'm guessing this document isn't actually Boot Camp-specific; it's just a guide to how the keys are mapped under Windows.)

You can try the combination Shift + Clear ⌧.

  1. Windows Key (on a Magic Keyboard with Numeric Keypad - US English - Silver) it is the Command Key.
  2. Type Onscreen and the On-Screen Keyboard Application appears.
  3. Select "Options" (Lower Right, next to Help)
  4. Enable numeric keypad
  5. You are done!

left shift + key over number 7

that works for me

    That's the Clear key, as already answered.
