A user interface is provided allowing a user to simulate mouse hovering with the user's finger on a touch-sensitive display. When a finger or other stylus touches the touch-sensitive display adjacent to a display cursor, a control appears that enables the user to drag the cursor about the display by dragging the control. Manipulation of the control instead of the cursor allows the user to see the cursor while it moves, making it easier to accurately target small objects that were previously difficult to target directly. In addition, a tap or other user touch input is funneled from the control to the location of the cursor itself. For example, if the user taps on the control, the tap causes an event such as a left mouse button down event to be generated at the location of the cursor as opposed to the location of the tap, thereby improving accuracy.
