A method, system, and apparatus for entering alpha-numeric and non-alpha numeric data without the use of a keyboard input device are provided. According to one method, a grid is displayed on a display screen that includes one or more alpha-numeric characters. Distinguishing characters are displayed adjacent to each alpha-numeric character. In response to receiving a selection within the grid, a determination is made as to whether the selected location contains an alpha-numeric character and, if so, a further determination is made as to whether a distinguishing character is present on two sides of the selected location. If a distinguishing character is present on two sides of the selected location, then the character located at the selected location is entered into a keyboard buffer as if a keyboard input device had been utilized to type the character. The grid may also include character strings corresponding to non-alphanumeric keystrokes that may be selected and entered into the keyboard buffer in a similar manner.
