Abstract
A method for operating an ergonomic computer keyboard. The keyboard may include a housing with a removable first input device in an upper surface of the housing and a second input device in a lower surface of the housing. Users may generate first and second input signals by manipulating the first and second input devices, respectively. The users may support the keyboard by grasping a projection projecting away from the lower surface of the keyboard housing. The users may also pivot end portions of the keyboard relative to a central portion of the keyboard while manipulating the first and second input devices.
