Abstract
A hand-held portable computer has a mouse button that is surrounded in close proximity by directional buttons. Placing the directional buttons in close proximity around the mouse button makes on-screen navigation easier, since the same single finger need only be moved by a small amount to actuate one or more of these buttons. If the mouse button is actuated, a mouse cursor can be moved about a page displayed on a display screen. If the directional buttons are actuated, the page can be panned around the display screen, while the mouse cursor remains stationary. The portable computer is also provided with a plurality of hot keys, and with buttons that are located off its keyboard, such as at the back of the portable computer.
