Abstract
An expandable keyboard with at least one keyboard sections stored in a nested manner inside a default keyboard such that the at least one keyboard sections can be extended in a telescoping manner from a housing of the default keyboard. The default keyboard comprises all the necessary keys to operate the computer so that the computer can be used even when the at least one keyboard sections is in a stored position. The expandable keyboard disclosed is particularly desirable for a portable computer in that it offers users a larger keyboard area comprising a more user friendly keypad layout yet does not add to the computer's thickness or lateral dimension so the computer remains easily portable.
