"The Editor You Need To Read (At Least) Two Books On To Use Well" Read :help. I haven't read any books on Vim so I'm not sure if there are any good ones, but you most definitely do not "need" to read one. "The point of a mouse is to make arbitrary on screen jumps efficient, and it’s very good at doing that. Don’t you ever think you can beat a mouse. Only in very few edge cases will it even matter." That's kind of rid…
Even if the mouse were quicker on average for long jumps, the moving of the hand from mouse to keyboard feels like more of a combo breaker, more distracting. Speed is very important, but equally important is for the editing experience to have a low attention footprint to leave more space for the train of thought behind the changes being made.
