Thanks house9-2. I briefly tried Dragon like six years ago and didn't have a very good experience with it—though I imagine it's improved since then. Probably the bigger issue for me though is that I just don't personally like speaking as an interface to coding. SmartNav looks cool. IIRC I looked into it way back when but it was prohibitively expensive for me, though I might be thinking of something else.
I'm mostly just using mouse/keyboard now, but I have learned some things about how to do it. Partly it's about not freaking out about things—seems like the added tension makes it a lot worse. That has been much more difficult than I can describe briefly here, but it was important at least in my case. Additionally, having some mindfulness about how I was feeling physically at the computer and letting that direct break-taking has been very useful. Same with various stretching/yoga things I do regularly. I spent a lot of time learning/practicing meditation in order to getter better, unadulterated feedback about physical problems (and to help stay relaxed while computing). It's interesting how oblivious we can be to discomforts from posture etc., and how automatic correcting them can be once you just tune in.
Anyway, I'm still not fully recovered either, but computing is a much more pleasant thing these days than it has been for many years.
