ABSTRACT:
A telephone handset comprises a front surface with a display and a keypad. The keypad includes a group of keys for entering alphanumeric signs and a key for navigating a cursor in the display. The navigation key is placed in the front surface of the phone between the display and the group of alphanumeric keys, and it includes a roller body which extends partly though an opening in the front surface of the phone. The roller body is essentially cylindrical with a length and diameter of the same size as the width of the keys in said group of keys for entering alphanumeric signs.
