> If you really are working in such a sweatshop where saving a couple of seconds a day is something you need to think about, then you have my pitty and condolences! At least for me, not every single waking second of my work day is spent hammering out code - I am probably only actively typing in new code perhaps 20-25% of the time max with the rest going on reading existing code, stepping through a debugger, dealing with tickets/bugs, running tests, doing emails, meetings etc etc.

The reason to not having to move your fingers/arms much is not about time. You just stay in the zone longer, you have less possibilities of distractions... It is about comfort and not disturbing the flow.

It's the same with music (wether is jazz or blues at least). Good intrumentists just don't move their hands much, lest their instrument goes in the way of their improvisation. 60% of the time, our job is quite boring, so make sure you really enjoy the 40% that's left.
