ABSTRACT:
A communications apparatus has a housing and a display and includes a first keypad device and a second keypad device. The first keypad device is immovably disposed relative to the housing and the display. The second keypad device is operative for moving to and between an exposed state and a retracted state. When the second keypad device is in the exposed state, the first keypad device is covered by the second keypad device so that the second keypad device is accessible to a user while the first keypad device is inaccessible to the user. When the second keypad device is in the retracted state, the second keypad device is stowed within the housing and the first keypad device is uncovered such that the second keypad device is inaccessible to the user while the first keypad device is accessible to the user.
