* The MouseEvent interface provides specific contextual

* indicates the number of times a mouse button has been pressed and
* released over the same screen location during a user action. The
* attribute value is 1 when the user begins this action and increments by 1
* for each full sequence of pressing and releasing. If the user moves the
* mouse between the mousedown and mouseup the value will be set to 0,
* indicating that no click is occurring.
*
In the case of nested elements mouse events are always targeted at the
* most deeply nested element. Ancestors of the targeted element may use
* bubbling to obtain notification of mouse events which occur within its
* descendent elements.
