I think anyone who does programming should at least give Neovim a good shot. Like, dedicate a few months to get a feel for the basic controls, use relative line numbers to jump to lines, f and F to jump to spots in lines, ciw ci" etc. to change stuff. If it's not your thing then fine, but learning Neovim is like switching from clicking file -> save to ctrl+s, but with everything.
You really don't need a mouse at all and in the end you'll get to make changes as fast as you can think. It's a language you speak through your keyboard to your editor and things just happen once you get fluent. E: checking if editing helps this thread federate better.
Thanks, I'll check it out!
