❓ 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 falseRun 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/
