ABSTRACT:
Several different symbols may be assigned to each key of the keyboard as requested by the operator. All the various symbols of the keys are recorded in a memory where they are organized in a certain number of pre-defined, distinct configurations of the keyboard. The configuration chosen by the operator is recorded in a display memory and displayed by means of a graphic unit on a flat panel, for example a liquid crystal display panel. The key actuated by the operator is identified by a decoding circuit to determine its symbol by means of the display memory and to display it on the flat panel.
