if keyboard were a subject, what knowledge would you need to possess in order to become 'proficient' at it?
I think the basics are:
Touch Typing
Knowledge of other typing layouts (QWERTY, Dvorak, Colemak, etc)
Basic knowledge of simple hand tools (screwdrivers, multimeter)
Basic keyboard shortcuts (CTRL-L, CTRL+SHIFT+ESC)
Soldering (Don't have to be good at it, just know what it is)
Basic researching skills (persistence, reading comprehension, how to search for things on Google)
