That old British comedy "Are you being served" might suggest another thing to try. The older lady had a cat and they used to use a different term for it. They'd say keep your (word) off the keyboard. I still think that stuff is funny and it is like 30 years old.

You could borrow a friends keyboard to try maybe.
