I long ago created a special script (in Macos it's via something called Hammerspoon, I used to have a Windows version).
It basically gives vim-like keys anywhere you want, when holding down the caps lock key. So e.g. caps+h/j/k/l are movement keys.
It goes a lot farther than that: I have a key to delete a line, a key to select a word, a key to go up/down by 4 lines, a key to delete the last word, etc. I even mapped caps+f to jump forward 20 characters (to badly simulate using 'f [letter]' in vim).
This makes so it I never have to leave home position on the keyboard, because while holding caps I have all the movement keys I want at my disposal. It's a total lifesaver, and the only way I can effectively use a keyboard outside of vim :)
