I wish you a speedy recovery. Such injuries can be more painful to the head than the limb and I hope you can stand the tediousness of it all.

Now, left-hand mouse ? I could never understand why any right-handed person would use the right hand for the mouse. I automatically started using the left hand so that my right hand was free for the keyboard, note-taking, calculator, sketching, whatever (go ahead Spaw). Yet, I know only one other person who uses the mouse "opposite-hand".
