jquery – Detect entered character with JavaScript

I\’d like to start an action (enabling autocomplete) when user types \’@\’. However I don\’t know how to do it correctly. I have jQuery available.

Usually on a QWERTY keyboard, it is like this:

$(\'textarea\').live(\'keydown\', function(e) {
  if (e.which === 50) {
    console.log(\'@ has been entered.\');
  }
});

However it does not work correctly on an AZERTY keyboard. The keyCode = 50 corresponds to the é~/2 key. To type \’@\’ in AZERTY keyboard, it is AltGr + à@/0 key.

Edit: I was not clear. Autocomplete starts when @ is entered, and only after that. Example, when someone enters \”Hello @\” then it starts, however when he types \”Hello @nothing else\” the complete won\’t do anything. Example: http://mrkipling.github.com/jQuery-at-username/ (it works only on QWERTY keyboard).
