According to the present invention there is provided a pearlescent unitary dose composition comprising a water-soluble film encapsulating a liquid treatment composition suitable for use as a laundry or hard surface cleaning composition having turbidity of greater than 5 and less than 3000 NTU, the composition comprising a pearlescent agent and from 2% to 15% by weight of the composition of water. A conductive coupling element of the displaceable member capacitively couples signals from the at least one drive electrode to ones of the sense electrodes underlying the conductive coupling element. Also, the invention distinguishes between key presses from a local, full sized keyboard and key presses from a remote keyboard so that the audiovideo playout program can enlarge its screen display when a key event is received from the remote keyboard. The fuel may be provided in various forms, configured to cooperatively engage said wick holder and support plate, and may comprise various volatile materials.
