I did and I found some options that have to do with alternative keyboard layouts, usually folding the keyboard in half using a hot key. I was lucky in that I had partial use of my hand and since my injury and surgery were so high up on my arm (as opposed to a direct hand injury) I wasn't as held back as I might have been otherwise.

I also looked into hardware solutions, but those are expensive and more for a person who isn't going to recover (longer learning time, more $$). At the time I also considered seeing if I could write something for my cell phone that would make using the keyboard on it with one hand easier too.

At the time, I certainly would have purchased a software solution if it was reasonably priced (maybe 33-50% the cost of hardware solutions).
