We should also consider that needing to type 100 words per minute isn't using a lever either. IDE's have gotten quite good, for example. How about adding voice input? Why can't I simply say 'build', 'run', 'indent line' or 'reformat code'? It also knows the 10 variables that are in scope in a function, so why can't I simply say the variable name that I want to type? Voice recognition should understand that I'm working in camel or snake case.

Of course, I'd like more complicated actions.

'Select line. Wrap in fast for loop'

'rename function'

'Open file x'
