Good point. About 15 years ago I had the beginnings of RSI, and discovered the immense benefit of just getting up and walking around every now and then (good for the eyes, too). Also there are a few wrist/forearm massages that helped, basically I just squeezed wherever it felt necessary.

I also changed my typing style to use my arms to slide my wrists around the keyboard a little rather than overextending fingers, and I rotated my hands inward about 30 degrees (maybe less, never measured it). I still keep about 60-ish WPM with this method, even at 42 years old.

Anyway, I like the Workman layout a lot, especially that the common move for index fingers is down, and the common moves for middle and ring are up. Great thinking!
