1. An apparatus, comprising: a display; a touch panel; a processor; and a non-transitory computer-readable medium encoded with instructions which, when executed by the processor, cause the apparatus to: display, in a region of the display, a portion of a scrollable display object including a plurality of respective items, the display object including an edge and having at least one of the plurality of respective items located adjacent the edge; detect a movement operation in which an operating object moves at least partially in a first direction along the touch panel while in contact with the touch panel; determine, during the movement operation, whether the edge of the display object has reached the region of the display; when, during the movement operation, the edge of the display object has not reached the region, scroll the display object in the first direction within the region; when, during the movement operation, the edge of the display object has reached the region, refrain from moving the edge of the display object in the first direction; detect, during the movement operation, an overdrag operation in which the operating object moves at least partially in the first direction at a time after the edge of the display object has reached the region of the display; and in response to detecting the overdrag operation and before the operating object releases contact with the touch panel, display, under control of the operating object, a graphic element in the region that at least partially overlays the at least one of the plurality of items adjacent the edge.
