Astram, I would use the method Crow described. In the end it should look somewhat like this:

PHP Code:

function GraalControl.onKeyDown(temp.keycode, temp.keystring, temp.scancode) {
  switch (keycode) {
    case 219:  this.selectedid = (this.selectedid - 1) % this.rights.size();  break;
    case 220:  this.selectedid = (this.selectedid + 1) % this.rights.size();  break;
    default:   return;
  }
  player.chat = this.rights[this.selectedid];
} 


That returns as a NULL value, you know?
