ABSTRACT:
A computer system has a computer display with two methods of navigation: discrete and continuous. In discrete navigation, a cursor is moved discretely using a set of arrow keys while in the continuous navigation, a pointer or other screen object has analog movement to any position on the screen using a trackball or other device. When the discrete navigational method is used to highlight a menu item in a menu on a computer display, the computer system masks the display of the pointer until re-activation of the pointer in the second navigational method. In addition, the computer system recalculates the location of the pointer to a position in the center of the highlighted menu item.
