Abstract

The present invention includes a device, method, and user interface for providing optimized entry of alphanumeric text. In one form, a method for providing selectable characters within a user interface includes determining an operating mode of a communication device and receiving an input associated with a selected input key. The method determines a group of characters associated with the selected key based on the operating mode and displays the group of characters within the user interface. The user interface may display a first character of the group of characters within a first portion of the user interface and the group of characters proximal to the first character within a second portion of the user interface.
