A system for controlling an apparatus ( 11, 21, 31 ), which system comprises a control unit ( 13, 23, 33 ) adapted to transfer control signals to the apparatus dependent on the control data. Said control unit comprises data input means ( 14, 24, 34, 44 ) to input said control data, and said apparatus comprises interpreting means adapted to translate said control signal into an action. Aiming to indicate for a user of the control unit, which action the apparatus is arranged to take when activating the data input means, a visual indicator is arranged on said data input means. The invention is characterized in that said data input means comprises a variable presentation means ( 45, 57 ), arranged to realise said indicator, wherein said control unit comprises a first storage means ( 53 ) adapted to store the visual data presentable with said presentation unit. Preferably, said control unit comprises several separate data input means, each provided with a presentation means, in which each presentation means comprises separate displays, arranged to present a picture dependent on said visual data.
