Abstract
A telephone keypad for one touch text messaging the QWERTY pattern of keys in a matrix of nine keys. Using the multi position biasing keys only one touch is needed for each character, so in use to input the letter “C” you touch one key one time, decreasing the time spend text messaging from cell phones or desk tops and dialing phone numbers advertised in letters. The keypad also has a shift key to get upper case included in the nine keys, and a 2nd key to double functionality of the keys.
