Answer 4

interesting question.
I have always heard the idiom as typing at the keyboard even though logically typing on the keyboard makes more sense. If we just want to be logical as opposed to idiomatic, I like the answer which said: I am at the keyboard typing on the keyboard. Given that language is a changing dynamic system, I would guess that in ten or twenty years, typing on the keyboard will become the idiom,

Answer 5

Typing AT a keyboard would say someone is infront of a computer, using it. Typing ON a keyboard would be centralized only on the keyboard itself, and the act of only typing.

Answer 6

typing ON a keyboard

Answer 7

Typing on, typing at is a location in space. You could use either one, but typing on a keyboard is a verb. Where is typing at a keyboard, at is being used as a verb but it is better used as a preposition
