jamesh asks: "I'm interested in switching over to an alternate keyboard layout, probably Dvorak, before I begin to suffer any effects of RSI. I'm almost 30 and have been typing since I was about 8, and these days spend most of my workday in front of a computer, typing away at a keyboard. I've searched the Internet and most people's comments are that within a few months they were up to or faster than their previous speed, with better accuracy. I'm mostly a programmer, but I do spend time at client sites and do need to spend time at various users computers to have a look at whatever hole they've dug themselves into, and so I will need to switch between QWERTY and Dvorak mode fairly frequently. What others have found when switching back and forth, as required? Can you mentally just flip back between them, or do you 'lose' your QWERTY skills and become 'hunt & peck' when faced with the old keyboard layout?"
