### getKeyboardModifiers

    public static int getKeyboardModifiers(Event event)

  Deprecated.
  Gets the keyboard modifiers associated with a DOMEvent.

  Parameters:
    `event` - the event.
  Returns:
    the modifiers as defined in `KeyboardListener`.

### fireKeyboardEvent

    public void fireKeyboardEvent(Widget sender,
                                  Event event)

  Deprecated.
  Automatically fires the appropriate keyboard event to all listeners. If the given event is not a keyboard event, no action will be performed.

  Parameters:

### fireKeyPress

    public void fireKeyPress(Widget sender,
                             char key,
