While we're doing asides: In days gone by I worked with a person who was regularly 2 or more full window switches ahead of Emacs. Meaning, they could type a switch window command and using their memory of the code and point there type a search/delete/change, switch to a 2nd window, do the same, etc all before the 1st window rendered.

Of course this was on slow computers so it was not so much a feat of speed but rather how much of the full code they were holding in their head at any time.
