You're right, it's a German QWERTZ keyboard (sorry for the low-res pic). Thanks for the video. I should be able to swap the Z for the Y, and figure out the rest of the keys from memory, once I set it as a US keyboard.
If anyone knows of a more thorough kit or guide to convert a QWERTZ keyboard to QWERTY, I would appreciate it. Thanks!
Swap Y and Z.
Replace all punctuation keys by buying US ones here.
Also replace all number keys except 1, 4 and 5.
Otherwise the tab/caps lock/shift/delete/return keys will look different, but still do the same thing.
In case it's helpful for anyone, I downloaded KeyRemap4MacBook (terrible name), and was able to make the Backquote into a Left Shift (as I was constantly missing it) and the Backslash into Enter (same), and the Section key into a Backslash. I'd rather have a US keyboard, but this will do.
