Abstract
The specification discloses a word processing system having a keyboard (10), a display (20), a processor (14) and a random access memory (22) for storing data and programs. The display (20) includes a first text area (24) wherein text entered through the keyboard is displayed. The display also includes a prompt line (26) through which all input between the operator and the word processing system occurs. The system provides deadkey compression wherein the depression of selected deadkeys on the keyboard causes the automatic generation of a required backspace in order to enable the construction of a diacritic character and the display of the constructed diacritic character in either the text display area (24) or the prompt line (26).
