Abstract

A technique to switch between upper and lowercase alphabetic characters in a wireless communication device measures the period of time in which a numeric key is held in the depressed position by the user.
If a numeric key is pressed by the user for a period of time less than a predetermined threshold time (212), the selected alphabetic character is displayed in a default character case. If the selected numeric key is held in the depressed position for a period of time exceeding the predetermined threshold period, the character case is altered and the altered alphabetic character is displayed for the user (214). The user selects the desired alphabetic character by activating a selected numeric key one or more times corresponding to the desired alphabetic letter. If the selected numeric key is held in the depressed position for a period of time exceeding the threshold period during any of the button depressions (212), the system automatically changes to the altered alphabetic character case (214). The alphabetic character case is controlled on a character by character basis such that entry of a new alphabetic character uses the default character case unless the selected numeric key is again held in the depressed position for a period of time exceeding the predetermined threshold.
