ABSTRACT:
Conflicting requests for cursor control of displaying are resolved by priority. The cursors can reflect attributes of their control or those of their control units, with visual attributes being color, shape or the like. Priority may be established between each cursor and a range of areas acceptable for cursor movement subdivided from the screen, or according to a priority of allowable functions, or according to a priority of conflicting operating times, or a combination of the same. Simultaneous control of a plurality of cursors can be permitted when there is no conflict.
