@Totalchaos, thanks for the helpful info. My ergonomic situation is not that complicated. I'm pretty much using the stuff available in Windows 7. The ease of Access Center (Win Key + U) has the Speech Recognition Software, and Mousekeys, which is for people with limited mobility that can't really use any type of mouse. I finally ditched the mouse after trying several of them; plain 2 button shipped with pc, logitech wireless, ambidextrous trackball, usb trackpad, The only good one was the corded logitech trackman wheel, but even that one would tire out my thumb. When I do my radio contests I hold the phone in my left hand/ear, hang up with my right index finger and hit speed dial button with my thumb in a back and forth manner, really quickly, many, many times. That's kind of why I stopped using a mouse. I didn't want to lose that speed. Even switching to left handed, after a few months you begin to have some discomfort. With voice recognition, there's no discomfort and the commands are easy. "Open Chrome browser", "Press ALT-D" "Show Numbers" puts a number on every link in a webpage, then you just say "click 22" .. "Mousegrid" opens up a grid that you can narrow down to even the smallest link in a page. The voice recognition software is great especially when I enter unlimited entry contests. I entered one 700 or so times and won a V.I.P 3 day theme park/2 night hotel + $1,000 spending cash.
