摘要

Input device has a display unit with a navigation unit linked to it. The latter comprises a four way tilting switch. Two of the tilting directions correspond to scroll directions, while the other two correspond to command input or selection directions. Use of the two control key directions enables a soft-key functionality to be achieved. An independent claim is made for a communications unit with a display and a multiplicity of display control elements or soft-keys each of which is assigned to a control function and is selected by appropriate control key activation.
