A display control module defines a first display area with a first boundary therearound and displaying a first category indicator for a first category therein. The display control module defines a second display area with a second boundary and displays a second category indicator for a second category therein. A gesture control module receives a movement signal from the user interface for moving the first display area relative to the second display area using a user interface. The display control module defines a third boundary around a third display area representing the first category and the second category when the first boundary and the second boundary touch or overlap and displays the first category indicator and the second category indicator within the third boundary. When the third display area is selected, a function may be performed.
