I don't have RSI, but I've felt strains and transient pains from time to time after hyperfocus computering. For me three things help a lot, to keep things "normal". 1. Avoid typing in the first place (seriously, avoiding the "Repetitive" bit is useful). Lots of typing stuff for me is thinking / revision stuff. So I do that in my head or on paper / whiteboard. 2. Put Ctrl under my thumbs as the lord intended https://en.wikipedia.org/wiki/Space-cadet_keyboard https://en.wikipedia.org/wiki/Space-cadet_keyboard so no Emacs Pinky. 3. Use chording for moving around / yank / kill etc. I also use Vim, but separately. Maybe EVIL will give similar results. But "methods to not need to type" category of stuff is probably the main thing for me. Also as some others note, "using body and strenghtening it" category of stuff is also fundamental to my, ah, process. IMHO strain injuries are rooted in mechanical imbalance as much as they are rooted in overuse. (Edit: added more detail, clarifications.)
