How Do You Function, When One Hand Is Out of Commission?

So, uh... cat bites are pretty bad, as it turns out. I was in the ER yesterday, after my sweet cat Franny sunk a tooth into the top of my left hand, causing it to swell up like a balloon. I'm now on a strong antibiotic and some stronggg painkillers, but it's still a baseball mitt-sized mit that hurts like hell in any position other than upright and can't be used. I'm typing with just my right hand, right now.

A blogger whose hand was injured by her own cat seems almost too good to be true, in a darkly humorous sort of way. I know. But it's extremely inconvenient and I'm sure there are better ways to go about this than typing with just five fingers. Mountain Lion dictation is supposedly great, but I don't have ML yet. And I've heard good thing of Dragon Dictation, too.

Have you ever had to deal with this? What did you do?
