Abstract
A method for operating a keyboard for a hand-held computer. In one embodiment, the keyboard includes first and second portions that are removably coupled to each other. The method can include removably coupling the second portion to one part of the first portion to block access to input keys of the first portion, and can further include removably attaching the second portion to another part of the first portion to allow access to the input keys, forming a full-size keyboard for a hand-held device. The second portion can be inverted to allow access to input keys on either a top or bottom surface of the second portion, and can also be pivoted relative to the first portion about an axis that is generally perpendicular to an upper surface of the first portion.
