Abstract

The present invention relates to a mobile communication device having a keyboard and a method for controlling the operation of the keyboard of such a mobile communication device. The keyboard provides a QWERTY styled layout including a keypad similar to a ITU-T keypad.Applications executed on the mobile communication device are adapted to switch an operation mode of the keyboard such that in accordance with a certain expected information input, different assignments of the keys of the keyboard are active. The keyboard operation modes improve the usability of the keyboard and allow the number of total keys for operating the mobile communication device to be reduced resulting in lowered cost of manufacture.
