A keyboard as presented here consists of a left and a right array of keys mechanically separated from each other and therefore arbitrarily positionable relative to each other. The keys are couplable to coding units generating the code signals necessary for the control of a data processing facility connected to the keyboard. The two arrays of keys, both essentialy of the same size,contain all the keys necessary for the input of data into the data processing facility and for the control of certain functions including a cursor. In addition to the usual switching device for the choice of capital and small letters and the like, there is an additional switching device so that a number of keys can be coupled alternatively to three or four different coding units.
