Before sending a key event while modifiers are active, send events for the modifier keys. Some applications don't look at the "metaState" flags but instead keep track of the up and down events for the modifiers. For example, the basic text views that are in every applications correctly handle the "metaState" flags except for one binding: Selecting text with the arrows while pressing shift.
