Abstract
A keyboard having a base and first and second demi-boards, which demi-boards include respective first and second key arrays. The first demi-board is supported in the base, and the second demi-board is supported in a variable elevation relative to the base. The elevation of the second demi-board may be selectively varied between a first elevation in which the first and second key arrays are substantially even relative to one another and a second elevation in which the first and second key arrays are substantially offset relative to one another. The second key array is operative in a first function mode when in the first elevation, and in a second function mode when in the second elevation. In one aspect, the second key array comprises first and second linked key rows, the second key row being moveable relative to the first key row so that the first and second key rows may be vertically aligned.
