Issue

Often times, when I press the caps lock key in insert mode or command mode, I forget to press it again to turn it off when we enter normal mode, and that can cause a lot of trouble.

So there is a solution for it for the regular vim that you use in a terminal.

Question

• Is there a way to use this "Insert-mode only Caps Lock" with VSCode Vim(extension)?
• Is there anyway I can turn off caps lock when I go back to normal mode from insert/command mode?
• Is there anyway I can turn off caps lock whenever Esc key is pressed (on MacOS)? https://unix.stackexchange.com/questions/61242/turn-off-caps-lock-when-escape-is-pressed
  (Maybe withe a help of a software like Karabiner Elements?)

What I've tried that didn't work

• Since VSCode supports ..vimrc, I created it and put this code, but it didn't work. (This works with regular vim in the terminal)

for c in range(char2nr('A'), char2nr('Z'))
  execute 'lnoremap ' . nr2char(c+32) . ' ' . nr2char(c)
  execute 'lnoremap ' . nr2char(c) . ' ' . nr2char(c+32)
endfor
autocmd InsertLeave * set iminsert=0

• I looked for a "Karabiner-Elements complex_modifications rules", but couldn't find what I was looking for.

Answer 1

Maybe sedleds and an autocmd like

autocmd InsertLeavePre * !setleds\ -caps

untested

I tried with import pyautogui ; pyautogui.press('CAPSLOCK') and that toggles the caps key, but I have not found a way how to detect if capslock is 'locked' or not. It would otherwise work with linux, windows and macos as it seems.
