Many of us are here (myself included) because of RSI. I just wanted to mention that I've gotten some help from "No Hands Mouse" by Hunter Digital. It has two foot pedals -- you move the cursor with one and click with the other. And your regular desktop mouse will work at the same time.
I would NOT recommend it for anyone with knee problems. And it is far from perfect in other ways as well*, but I'm getting the hang of it, and since mousing seems to be worse than keyboarding for me, it's really helped. And it does come with a 30-day money back guarantee.
I had one on back-order for the longest time -- turned out Hunter Digital was out of a part and completely out of stock. But I used their website's list of distributors (see link on http://www.hunterdigital.com) to find one that still had a couple in stock; received it two weeks ago. (You could see if Hach in the Carolinas still has one left.)
*Mouse has to compensate for the constant pressure your foot exerts on the pedal, by damping it. So when you take your foot off the pedal, the cursor moves, often in unexpected directions, rather than staying put. And I find that clicks often don't work if the cursor is moving -- which is a problem, because it's VERY hard to get the cursor be completely stationary (while foot is on the pedal, too, which is the normal mode of operation). Given this, it is wonderful that the regular mouse is still hooked up and working while one uses the foot mouse.
I'm using it on NT.
I will in no way profit from anyone's purchase of one of these mice. In fact, I'd be interested if others have found other helpful adjuncts to DNS.
