Abstract: 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.

Abstract: On a paging receiver visual symbols are visually reproduced, relative to one another as in a two-dimensional scene, under the control of a message received.

Abstract: A consumer appliance having both explanatory comment and extra-linguistic signalization upon actuation thereof and reversible stepping between those two.An electronics-controlled consumer appliance has various hardwared actuator elements for through actuation thereof driving the appliance from a present state to an associated respective destination state. It also has audio output for under control of selected present state-actuation combinations outputting a specific audio specifier. By way of improvement the specifier comes in a two-tier organization: in an upper tier it outputs an explanatory audio comment and in a lower tier it outputs an extra-linguistic audio signalization. Furthermore, the device allows for selectively and reversibly stepping between said two tiers.
