A rubber-band gesture begins with a source touching a touch display at a touch-down location of the touch display. The rubber-band gesture continues until the source stops touching the touch display at a lift-up location of the touch display. An action is displayed on the touch display in response to the rubber-band gesture. The action is displayed in a direction parallel to a vector pointing from the lift-up location to the touch-down location. The action is displayed with an action amplitude derived from a distance from the touch-down location to the lift-up location.
