I have a couple of Microsoft Trackballs; I found that the constant moving back and forth with the mouse was a disaster for me. Unfortunately, I bought the second because the first was so good and I'd heard MS were withdrawing them from the market.

Take time away from the keyboard, use your non-dominant hand with your phone. At least, this helps me.
