Abstract: A method and computer program product are provided for operating a device having a housing section carrying a touch-sensitive display and a physical keyboard section movable in a sliding direction relative to the housing. A position detector determines a position of the physical keyboard section in relation to the housing section. A processor displays a graphical element on the touch-sensitive display when the position of the physical keyboard is closed and displays no graphical element when the position of the physical keyboard is open. The position detector is one or more of a magnetic sensor, a mechanical switch, or a touch controller coupled to a capacitive touch detection sensor matrix carried by the physical keyboard section. The graphical element may be a virtual keyboard. The virtual keyboard is displayed as a scrolling animation correlated to the position of the physical keyboard section.
