Shortcut Selection of Alpha Characters in Cellular Phones

      Cellular telephones are becoming smaller. Smaller telephones which support text messaging omit a regular keyboard in favor of the alphabetical characters in each numerical key. The problem is there is a limited number of keys, and some numbers would have to be pressed two or three times for specific letters. For example, the #2 key also have letters 'A', 'B' and 'C'. To get letter 'C' in a text message, the #2 key would have to be pressed three times to go through the sequence 'A', 'B' and finally 'C'. The problem is it takes longer to type a text message if a key has to be pressed few times for a character.

    The system cuts time by allowing an user to press and hold a button on the side of the phone and press the numerical key once to get the second letter, and a different button to get the third letter. The advantage is it takes less keystrokes to type a message, reducing the time it takes to type a message. The Figure below shows a cellular phone with two buttons on the side. An user can hold the phone in his/her left hand, using the thumb to select letters while using the forefinger to hold down the top button for the second letter and using the middle finger to hold down the lower button for the third letter. The user may also dial the keypad with the other hand. The buttons for choosing the second or third letters may also be on the other side for right-hand usage.
