Keyboard arrangement and mobile communication device incorporating same

摘要

The array of keys constituting a numeric phone keypad on a mobile communication device only partially overlaps the array of keys that make up the text input keypad creating an offset so that only subsets of the keys constituting the two keypads are common to both. With this configuration, the numeric phone keypad can be more easily distinguished from the text input keypad while still reaping the benefits of having some shared keys.
