focusController	Return the focus controller for this element.
focusIndex	An integer used to sort focusables in the focus ring. A negative value means that the element can not be focused.

Blur	Tell the element to release the focus.

HasTrickleDownHandlers	Returns true if event handlers, for the event propagation TrickleDown phase, are attached to this object.
