ABSTRACT:
A cursor tool is assigned to a cursor and a first cursor control event is performed. If a predetermined time interval expires before a second cursor control event is performed, the cursor tool is activated. The first cursor control event may be a mouse down event and the second cursor control event may be a mouse up event. In another embodiment, a plurality of cursor tools are assigned to a cursor and a sequence of cursor control events are recognized. The sequence may begin with a mouse down event. If one or more mouse move events follow, a determination as to whether these are intended events is made. So long as no tools have previously been selected, if the mouse move events are determined to be intended events, a first of the assigned cursor tools is selected. Alternatively, if the mouse move events are not intended events but the events occurred after a preestablished time limit, a second of the assigned cursor tools is selected. If a mouse up event is then performed, and no cursor tool has yet been selected, a third of the assigned cursor tools is selected and the appropriate cursor tool action is performed. Otherwise, if a cursor tool was selected before the mouse up event, the action associated with the previously selected cursor tool is performed after the mouse up event.
