Resolved Typing problem with key pressed: single numbers/letters only

Hello, from today i have this strange problem, if i keep pressing on any number/letter, it only types it ONCE and not continuously. This doesn't happen with symbols. If i keypress on .,-%$£"= i can keep pressing and it writes them until i stop pressing. This happens in every app, safari, notes, finder, textedit, word, pages, BUT not in Terminal. In Terminal everything works fine. If i press X and keep pressing it, it writes X until i stop pressing that key. So what couòd happne to my mac in one day? I didn't install anything, nor modified.


EDIT: nevermind, means that since LION i have never key pressed endlessly any key.

defaults write -g ApplePressAndHoldEnabled -bool false
