For computer work, I use a split keyboard. It allows me avoid internally rotating my shoulder. I highly recommend it. Split keyboards can be kinda expensive. It can be tested out cheaply by using a laptop and external keyboard -- left hand on the laptop right hand on the external keyboard. If you have a mac, I had to install karabiner to get keys from both keyboards to work in concert (e.g. to enable left shift and right 'k' to capitalize k).
