❓ What?

MacOS has this behaviour where if you hold a key, such as in my case, holding k to move up in VSCode, a special character popup appears where you can choose an alternative character for the key pressed.

🎤 The fix

defaults write -g ApplePressAndHoldEnabled -bool false

Run the command in your terminal app of choice, close/reopen app or logout/login or simply reboot. Since I am an uptime masochist, I simply close and reopen apps.

I am not sure if a help page exists inside MacOS to query the different values of the keys for defaults. However, in my search, I found this page which serves as an alternative: https://macos-defaults.com/
