The keyState variable is not declared in the keydown event function

[pandora-y]

_proto._keydown = function _keydown(e) { var handler = null, index, index2, keyBindKeys, allModifiersPressed; var pressedKeys = [], pressedModifiers = {}, currentKey = e.which, pressed = 'p'; keyState[currentKey] = pressed;

  for (index in keyState) {
    if (keyState.hasOwnProperty(index) && keyState[index] === pressed) {
      pressedKeys.push(index);

      if (parseInt(index, 10) !== currentKey) {
        pressedModifiers[index] = true;
      }
    }
  }

keyState should be declared.
