I've been concerned about my hands for a ways now, and have ordered a chording keyboard to alleviate them. I've also changed how I type with normal keyboards lately, and this recently led me to a more general observation. I've easy access to the control and meta modifier keys with each thumb, due to configuring my keyboard in software, but not with those shift keys, which require I move my hands to reach them. I use Emacs' word commands, bound behind the meta key, to obviate the need for using it in most cases. By splitting capitalization and such things into a seperate task after other typing, I considered how to remove the need to manually do so at all, and realized that task was mechanical.
Similar thoughts have me consider how many unnecessary keypresses are made because most text editors have no concept of the words they're typically used to enter, and so have little or no facilities to complete them, once an unambiguous front is provided. It's not very difficult to look at anything a normal computer is used for that isn't wasteful of human effort, and which should be automated once.
It happens that model of chording keyboard I've ordered will make it particularly easy to capitalize letters, and understandably make typing the complex chords I'm accustomed to far less convenient, so I expect to allow it to reshape my work in more ways than one, but I still find it valuable insight.
So, splitting a task into perhaps unreasonable pieces may lead to realizations of a mechanical task.
