I bought my computer, a macbook laptop, in December. I do not know where my num lock key is. I believe that this is (basically) my computer: http://www.apple.com/macbook/ -----------> from that link, click on the view of the keyboard to see it. My computer keyboard is exactly like that, except that the keyboard shown for that computer is different in these ways: 1. I don't have any pictures on my f5 and f6 keys. 2. On my command keys, it does not have the twisty symbol next to cmd. It has the twisty symbol on the top, and on the bottom it says command. 3. The control keys on my computer have the word "control" spelled out, they do not say "ctrl". With my computer's keyboard, how do I put on num lock?
