Abstract
Abstract An extension provided on a wireless telephone unit allows the unit to be compact while still providing an enhanced display, a keyboard, and a data input device. The keyboard is disposed on the extension which is slidable between a retracted and an extended position. When in the retracted position, the extension covers the data input device and most of the display. A single line of text remains uncovered for use when the extension is retracted. In the extended position, the extension uncovers a large display and data input device for use by the user.
