Abstract

A mobile station having a touchscreen display and function key allows users to quickly input data. The mobile station displays key input sectors including displayed representations of data characters for the user to select. Upon touch by the user, the mobile station senses the location of the touch and highlights the displayed representation of the corresponding data character. While the data character is highlighted, the user further activates the mobile station and the mobile station senses the user'"'"'s selection of the highlighted data character. The mobile station processes data corresponding to the selected data character as the user input data.
