ABSTRACT:
A method and apparatus for managing controls on the screen of a computer controlled display. The preferred embodiment of the present invention provides for quick and efficient activation and deactivation of controls by designating a number of controls as a control grouping. The preferred embodiment then collectively activates or deactivates the designated number of controls using an identifier for the control grouping. Additionally, after a user terminates cursor movement, the preferred embodiment automatically positions a cursor on an ideal control. The preferred embodiment determines the ideal control (1) by removing from consideration any controls which are (a) not visible to the user, or (b) located at non-optimal positions on the screen, and (2) by calculating a weighted distance for each remaining control. The preferred embodiment calculates the weighted distances by comparing the previous cursor movements made by a user with application specified parameters. After calculating a weighted distance for each remaining control, the preferred embodiment automatically positions the cursor on the control having a smallest associated weighted distance.
