"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…
For years I believed that eschewing the mouse was speeding me up. But I recently had the pleasure of working with a fine gentleman, and a SublimeText user, who is an absolute fiend with the mouse. He has considerably more development experience than I, so it is not an unbiased comparison, but I believe his raw editing speed was a bit faster.
This confirmed my suspicion, originally triggered by reading about the Acme[1][2] editor in Plan9, that such a workflow can be quite efficient.
