Abstract

The specification and drawings present a new method, apparatus and software product for combining scrolling with a multi-function key performance. A scrolling multi-function key module can comprise a multi-function key unit and a scroll touch sensor unit having an edge-like sensitive area substantially around the multi-function key unit for providing a scrolling movement of information, corresponding to the predetermined task and to the sliding movement of the object according to a predetermined criterion, on a display of an electronic device. A sensor module of the scroll touch sensor can comprise a plurality of electrodes (e.g., 4 capacitive electrodes) arranged in rows and columns to form a matrix and configured to provide Cartesian coordinates.
