A handheld control device of a system is coupled to a display screen comprising a number of lines. The device comprises a pushbutton for each line. The user can scroll through a series of possible contents of a line associated with a pushbutton, but only if the relevant pushbutton is depressed. Changing the contents of the line by the user thus becomes a coherent operation, so that the device will less readily respond to unintentional actuation of the controls.
