Recently I wrote a post on how to remap your Caps Lock key in a context sensitive way using KeyRemap4MacBook. Since then (just now) I have started to use my Mac laptop with an external keyboard. Not anticipating any issues, I got a little scared when the key remap I’d spent a while investigating and setting up didn’t work. It is with great relief that I now post the solution. You also get a bonus tip if you make it to the end of the post.
