ABSTRACT:
A data entry device with a keyboard for use with a data processing system. A first data set of input keys are arranged in a standard typewriter configuration. A second set of keys comprises additional rows of data input keys that enable the operator to enter various special characters or symbols that are encountered in different languages. One row of keys in the first set constitutes a variable row. A legend corresponding to a selectable set of symbols is juxtaposed to the variable row. An operator can select a set of characters so that each input key in the variable row thereafter functions to identify the character designated in a corresponding position of the juxtaposed legend.
