ABSTRACT:
An electronic device (1) comprises preferably at least a keyboard (4), which comprises at least one key (15a,15b) for controlling the functions of an electronic device (1). This keyboard (4) is arranged as a keyboard plate (16). Said keyboard (4) is implemented so that it also comprises a touch sensitive element (19), over which said keyboard plate (16) is arranged so that the depression of a key is arranged to be transmitted to a touch sensitive element (19) essentially at the point of a key (15a,15b). In addition, the electronic device (1) comprises means (21, 22b) for determining the point of depression from the touch sensitive element (19), whereby on the basis of the determined point of depression it is determined which key (15a,15b) has been depressed.
