First Claim
1. A telephone handset having a front surface with a display and a keypad, wherein said keypad includes a group of keys for data entry and a key for navigating a cursor in the display and selecting an item in dependence of the position of the cursor:
- said navigation and selection key positioned in the front surface of the phone between the display and the group of data entry keys;
said navigation and selection key includes a roller body acting as a navigation key which is essentially cylindrical with a length and diameter of substantially the same size as the width of the keys in said group of keys for entering alphanumeric signs, and extends partly through an opening in the front surface of the phone, and has an axis of rotation perpendicular to the longitudinal axis of the phone;
said roller body is fully rotatable and is allowed to adopt a predetermined number of valid positions during a rotation for moving the cursor, and can be depressed to request performance of an action in dependence of the position of the cursor, the structure of the navigation key comprising;
a roller body acting as a navigation key;
a carrier for carrying said roller body;
a supporting means supporting said carrier;
said carrier being hinged relative to the supporting means by cooperating hinging parts;
biasing means for urging the carrier and the supporting means away from each other at a distance from said hinging parts; and
detection means for detecting a force counteracting the biasing force provided by said biasing means and for providing a second control signal in dependence thereon.

10. A navigation key for providing control signals in dependence on the operation thereof, comprising:
-
a roller body acting as a navigation key; a carrier for carrying said roller body, wherein the carrier comprises a shaft part retained between two plate-shaped end parts, said roller body is arranged rotatably on said shaft part, and said end parts are furthermore adjoined by at least one beam-shaped leg part extending along the shaft part for providing a stiff structure for the carrier; two leg parts in parallel with the shaft part, the hinge part of the carrier extending outwardly from one of said leg parts; a supporting means supporting said carrier; said carrier being hinged relative to the supporting means by cooperating hinging parts; biasing means for urging the carrier and the supporting means away from each other at a distance from said hinging parts; and detection means for detecting a force counteracting the biasing force provided by said biasing means and for providing a second control signal in dependence thereon. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
