Abstract: A keyboard for an electronic device includes a first key having a touch surface which, in one mode, is responsive to pressing by a user's finger to indicate a selection associated with the first key, and an array of sensors exposed at the touch surface to detect, in another mode, the location where a finger is positioned on the touch surface as an indication of information to be conveyed by a user. The keyboard also includes a second key having an array of sensors which are exposed at a touch surface of the second key and which are sensitive to manipulations of a finger on the touch surface to provide signals used for switching the first key from the one mode to the other mode.

Abstract: A storage cabinet for storing in each of a number of stacked storage regions a boxed compact disk, a boxed compact cassette or a pair of unboxed compact cassettes includes a pair of opposed parallel side walls cantilevered from a rear wall and having stacked opposed pairs of protrusions defining a first storage region extending between the side walls for receiving a boxed compact disk or a pair of unboxed cassettes and each having a shelf spaced from the rear wall for defining a second storage region of width corresponding to that of a boxed compact cassette and depth less than the width of a boxed compact cassette for storing a boxed compact cassette so that it protrudes slightly beyond the free ends of the side walls.
