Control signals for a process displaying graphical objects in a display are generated with a first control surface, a second control surface and detector means. The first control surface is available for manipulation with a thumb of one hand on one side of a hand-held electronic device. The second control surface is adapted for manipulation with another finger of the same hand. It is located on a different side of the hand-held electronic device. The detector means jointly detect how the first and second control surfaces are manipulated, and convey information about detected manipulation of the first and second control surfaces further to generation of the control signals.
