Earlier quoted context omitted.
you do not need to install it anywhere... its already everywhere ( I am vim enthusiast ) for eg: Keep right hand free for writing/eating by reserving left hand for mouse. (keep same settings for right handed mouse) Brrrr... :p
So would the use-case mostly be for people who edit lots of files over shells? I guess I was mostly thinking of coding stuff. Or do people use it for coding too?
I've been doing that since the early nineties. First vi, later Vim.
I like it better than Visual Studio, better than Eclipse and way better than VScode.
