The second patent titled "Text Entry Interface for a Portable Communication Device" describes the process of displaying one or more characters that were selected by a user via a click-wheel in a first tray, while a second tray includes various icons that correspond to a set of characters and one or more recommended words in what appears to be an attempt by Apple to 'auto-complete' a word or phrase to speed typing efforts. A third patent describes segmenting a click-wheel's circular shape into various regions to enable quick phone dialing by sensing which region was touched, dialing the number shown in that region of the clickwheel on the corresponding screen.
