keyboard opitimized for the left thumb?
Can people recommend a keyboard opitimized for one-handed, left thumb use? The best one I've found is Thumb Keyboard 4 because, by providing an option to squeeze everything toward the left side, I can at least reach everything one-handed, even if it's still a bit awkward. I've tried several that allow shifting the entire keyboard toward the left, but I really need access to cursor keys and symbols, and so far Thumb Keyboard is the best. Are there any others to try?
