ABSTRACT:
In a data processing system, an object is displayed on a display coupled to the data processing system. Also displayed, is a multiple-point cursor having at least first and second pointing spots. The multiple-point cursor is typically positioned by user manipulation of a pointing device, such as a mouse. In response to a user indication, such as a mouse click, a first operation is performed on the displayed object if the first pointing spot is positioned over the object during the mouse click. Similarly, a second operation is performed on the displayed object in response to a user indication while the second pointing spot of the multiple-point cursor is positioned over the object on the display. Such first and second operations may include a copy operation and a move operation.
