  2591. * Procedure PostKeyEx32
  2592. *
  2593. * Parameters:
  2594. *  key    : virtual keycode of the key to send. For printable
  2595. *           keys this is simply the ANSI code (Ord(character)).
  2596. *  shift  : state of the modifier keys. This is a set, so you
  2597. *           can set several of these keys (shift, control, alt,
  2598. *           mouse buttons) in tandem. The TShiftState type is
  2599. *           declared in the Classes Unit.
  2600. *  specialkey: normally this should be False. Set it to True to
  2601. *           specify a key on the numeric keypad, for example.
  2602. * Description:
  2603. *  Uses keybd_event to manufacture a series of key events matching
  2604. *  the passed parameters. The events go to the control with focus.
  2605. *  Note that for characters key is always the upper-case version of
  2606. *  the character. Sending without any modifier keys will result in
  2607. *  a lower-case character, sending it with [ssShift] will result
  2608. *  in an upper-case character!
