/** makes it possible to receive keyboard events.
*
* This key handler is similar to com::sun::star::awt::XKeyListener.
* But this handler is easier to use and more flexible for many
* purposes.
*
* This handler is usually added via
* com::sun::star::awt::XUserInputInterception to the controller from
* com::sun::star::frame::XModel. While
* com::sun::star::awt::XKeyListener needs to be added to exactly the
* correct widget.
*
* Also this handler is more flexible then
* com::sun::star::awt::XKeyListener, because it optionally allows the
* consumption of key events. If a key event is consumed by one handler
* both the following handlers, with respect to the list of
* key handlers of the broadcaster, and a following handling by the
* broadcaster will not take place.
