I've never understood the sentiment that using a mouse is bad. I see blog posts all the time about how a programmer's job is more thinking than writing code and/or writing good programs is also about taking out just as much code as you put in. So if writing programs is a deliberate and methodical process that - I'd argue it's also slow. Why then is there antithesis that mice slow you down and you need keyboard shortc…
I suspect a lot more of it is perception than people imagine: keeping your hands on the keyboard all the time seems like it intuitively must be faster. Early research in human-computer interfaces suggests that this isn't actually the case, though. From 1989: "We've done a cool $50 million of R&D on the Apple Human Interface. We discovered, among other things, two pertinent facts: (1) Test subjects consistently report…
However, with regards to your example, things like easy motion/avy solve this exact problem, I think no slower than a mouse. You basically punch in one, two, or more characters at the place you want to jump (depending which package/command you call), and then every match on the screen is highlighted and replaced with a different letter. Then you press that letter and jump there.
Not arguing that's it's much better, just that's approximately the same. Check it out: https://github.com/abo-abo/avy.
