How to disable special character selection popup when a key is held down

Question

There was a fix that worked with Lion in this question

defaults write -g ApplePressAndHoldEnabled -bool false

but that no longer seems to work in Mavericks.

Has anyone figured out how to turn off the special character insertion popup that appears when you hold a key down in Mavericks?

Answer 1

That command still works in Mojave, High Sierra and Mavericks — don't forget to reboot or logout/login after running the command.
