Aha, right, cursor movement across large distances is indeed more comfortable with the mouse. This is usually awkward with the keyboard, and requires plugins like EasyMotion, or just holding keys or repeating key combos. I think these movements are rarer than small cursor movements, like jumping to the next character, word, line, etc., or jumping to the matching brace, etc. In these cases using the keyboard is still faster and more precise.
But I was more thinking about controlling the editor itself. Creating new buffers/panes and switching between them is all much faster with a keyboard. For example, I bind `=` and `-` to switch to the previous/next buffer, and Tab to switch to the next pane. I do these actions hundreds of times a day, and they're just a keystroke away. I couldn't imagine having to use the mouse for this. It would be unbearably slow and tedious.
The best part of key bindings is that they can be easily modified to suit any workflow. Whereas with mouse movements you really can't customize them beyond which of the few buttons to click. The movements themselves can't be optimized, unless you go into gesture territory, which has a lot of drawbacks as well.
No, it doesn't look like the Go font, but thanks.
