I have recently upgraded to OSX Lion, and I have to say that I love everything about it. Except for one thing. In many apps, the key repeat has been disabled in favor of the new press-and-hold popup for getting alternative characters.

This is fine for most apps, but for apps like PyCharm where I use vi key maps, it becomes very, very frustrating.

I came across this little tip to re-enable the key repeat, and my life is measurably better (first world problems, I know…).

Run the following in your Terminal.app:

$ defaults write -g ApplePressAndHoldEnabled -bool false

Then reboot, and you should be good to go!
