ABSTRACT:
A method and apparatus is described for reducing the width of a keyboard, such as a keyboard of a portable computing device, for folding the keyboard from a first width of the keyboard in operative position to a second width of the keyboard in a storage position. The keyboard has a plurality of keyboard sections each having a plurality of keys, where the operative position of the keyboard has the sections disposed in a line. The keyboard folds such that the keyboard sections are vertically adjacent to each other. The keys of the keyboard sections are compressed for storage to take up their travel and thereby conserve storage volume as well as storage width. Multiple implementations are disclosed, including keyboards that fold such that the keys of one section are in contact with the keys of another section, and keyboards that fold such that the keys are not in contact with keys of another section.
