Abstract:
A method of using a twelve key binary keyboard having a first set of nine binary keys numbered one ""1"" through nine ""9"", used as an alphanumeric binary keyboard, with twenty-six characters and a space grouped in sets of three's on all nine keys, combined with a second set of three binary control keys including, a first binary control key, a second binary control key and a third binary control key, using a control means comprising the steps of:a) activating one binary key of said first set of nine binary keys numbered one ""1"" through nine ""9"" or activating said second binary control key of said second set of three binary control keys, numbered zero ""0"", for producing a one key numeric value while in a standard number mode;b) wherein activating said third binary control key, while in said number mode, when not followed by the activation of said first binary control or said second binary control key, followed by the secondary activation of said third binary control key, when not followed by the activation of said first binary control key or said second binary control key, deletes all numeric data;c) activating said first binary control key only of said second set of three binary control keys for exiting said standard number mode and for entering a two key upper-case alphabet mode with twenty-seven data characters, including a space and one of twenty-six data characters of an alphabet;d) activating one binary key of said first set of nine binary keys numbered one ""1"" through nine ""9"" combined with activating one binary control key of said second set of three binary control keys for producing one of said twenty-seven data characters;e) producing one of three data characters represented on each binary key of said first set of nine binary keys numbered one ""1"" through nine ""9"", while in said alphabet mode, by selecting a data character, of three possible data characters;producing a first position upper-case data character by activating the desired data character's binary key combined with activating said first binary control key of said second set of three binary control keys,producing a second position upper-case data character by activating of the desired data character's binary key combined with activating said second binary control key of said second set of three binary control keys,producing a third position upper-case data character by activating of the desired data character's binary key combined with activating said third binary control key of said second set of three binary control keys,f) wherein activating said first binary control key, while in said alphabet mode, followed by the secondary activation of said first binary control key, followed be the trinary activation of said first binary control key, deletes the previously entered word;g) activating said third binary control key combined with activating said second binary control key, of said three key binary control set, for exiting said alphabet mode and returning to said number mode.
