Abstract

In a method and apparatus for assigning the values or functions to be represented by the keys of a keypad in a mobile communication device, the keys are capable of representing different values or functions based on the occurrence of a predetermined event. A detector is used to detect the occurrence of the event. Depending on whether the event is detected, the keys are assigned to represent a different set of values or functions.
