Obscure button tier list
(sh.itjust.works)
If you have "Help" instead of "Ins", replace it with Overgod-tier. Keep pressing it, it will come.
OC, feel free to share.
EDIT; Home is now G-od tier. I didn't know it would go to the beginning of a line, I always used macros "lol".
I've only had issues with embedded serial consoles and things where you have to swap ctrl-h/? for backspace. But usually it's solvable with key mapping.
Also you mention vi/m but insert is red? That's the toggle switch between insert and replace mode (i vs shift-R)
