A novel click-less tool system for performing user input device actions on computer systems, such as mouse clicks, automatically and without the need to mechanically perform these actions. All input is carried out by moving the cursor only. The system provides a user with visual trigger windows arranged near the position of the cursor on the screen and which becomes visible for a short period of time whenever the user mouse/input cursor stops. When the user moves the cursor and hovers over one of the visible activator windows, the click-less tool program automatically performs a preprogrammed action, then places the cursor back to where the user stopped before the trigger windows were visible. Once the action is performed the trigger windows disappear.
