Abstract (en)
[origin: EP0397019A2] The subject of the invention is a keyboard for inputting control and adjusting commands into a data-processing installation which is connected to adjustable elements in a spatially distributed installation. The elements can be switched on and off. An illustration of the installation, shown at least schematically, is arranged on a keyboard indicator panel. Selection keys (15 - 27) with light indicators are allocated to the adjustable indicators on the keyboard indicator panel, at the corresponding points of the installation. Further functional keys, of the same type as the selection keys (15 - 27) and provided with light indicators, are arranged in a separate area (28) of the keyboard indicator panel. <IMAGE>
