Intellij-idea: auto-repetition of letter keys

Question

Using Intellij-Idea 12 on OS X, I have a strange problem: when I keep a letter ([a-z]) key pressed in the editor, the key stroke does not repeat. This is unfortunately a problem

Answer 1

It's a system preference not specific to Intellij IDEA:

defaults write -g ApplePressAndHoldEnabled -bool false
