Typing strikes me as one of the few things that /wouldn't/ be harder
in microgravity. Certainly the astronauts are using keyboards a lot.
(One thing that's bitchin' hard, by the way? Turning a screw or,
worse yet, a nut.)
Typing may be an exception, but as a general rule you want to have
really strong wrists and hands. Apparently a lot of hand-related
activities use gravity for bracing. It goes unnoticed.. but absent
gravity, you have to do the bracing yourself. So, astronauts are
encouraged to do a lot of hand exercises.
ObSF: one SF work predicted this! Major author, but obscure minor
work.
