  • presentation logic for displaying on a presentation device an alphabet arranged into a row of letters, the presentation logic including logic to display a string field for presenting an alphanumeric string of characters selected by a user;

    indication logic, cooperative with the presentation logic, for presenting visual cues grouping a series of letters of the row into a cluster of letters to aid in the navigation of the row and the selection of a desired cluster;

    navigation logic, cooperative with the indication logic, for receiving user actions from an input device to move the visual cues along the row of letters to change the letters grouped into the cluster, the visual cues moving along the row of letters in variable offsets based on a rate of input of the user actions, wherein the visual cues move by a single offset for each user action in response to user actions entered at or slower than a predetermined rate, and wherein the visual cues move by more than a single offset for each user action in response to user actions entered faster than the predetermined rate; and

    selection logic for receiving user actions from the input device to select the cluster of letters to cause at least one of the letters of the selected cluster to be displayed in the string field.
