I use the following command to enable the "Press and Hold" functionality which is important for me to write text with language characters:
defaults write -g ApplePressAndHoldEnabled -bool true
However, every now and then for some reason setting gets reset and only starts working again after a reboot.
How can I have this setting be permanent without anything else interfering with it?
Update: at least in some (all?) cases the value is still true, but the popup does not come anymore until I reboot.
