Abstract
A method and computer system detects when a user of a computer depresses and releases a modifier key, for example, the CTRL key. The computer is programmed under a routine to locate the position of an active point of a cursor that is displayed on a computer screen. The computer thereafter generates and sequentially displays on the computer screen, concentric rings of decreasing size that radiate inward, centered on the active point, to thus help a user visually locate the cursor on the computer screen.
