Changing the keyboard repeat rate on macOS

I knew about Settings: System Preferences » Keyboard » Key Repeat/Delay Until Repeat

But it’s possible to make it even faster:

defaults write -g InitialKeyRepeat -int 10 # normal minimum is 15 (225 ms)
defaults write -g KeyRepeat -int 1 # normal minimum is 2 (30 ms)
