Abstract
Abstract A storage method and control system for creating linguistic expressions such as natural language text by both sequential and simultaneous keypresses. The system controls a programmable digital processor to receive keypresses from the operator and to translate groups of keypresses to linguistic expressions or not to translate, according to (1) the timing of the keypresses, (2) the presence or absence of a delimiter character at the beginning or end of a group of keypresses, (3) the presence or absence of the group of keypresses in a dictionary of stored groups of keypresses, and/or (4) the sequence of keypresses that preceded or followed the group.
