Ok - I know I may be downmodded for this but wouldn't it just make more sense to switch to an editor that maybe doesn't cause you RSI problems? All I'm saying is that if you have to go through so much pain and trouble to use a piece of software then just maybe it's not right for you. Also I'm not suggesting Vi but Emacs has a pretty good Viper-mode that may help with RSI issues. I use EMacs with Viper and I can prett…
I think it makes more sense to try to fix the problems the way Bill has than to give up on an editor which (we emacs users think) is incredibly productive. Besides, it may be that RSI will follow you to whatever other editor you choose.
That was the case for me, in fact, and I fixed it years ago by switching to a cheapo $30 Microsoft Natural keyboard.
