A USB touchpad looks like a standard touchpad with an attached cable that plugs into the USB port. The touchpad itself is a slightly rectangular pad with a touch-sensitive surface. The lightest swipe of a fingertip controls cursor movement, and taps emulate clicks. Scrolling is accomplished by sliding a fingertip up or down the vertical edge of the pad, or along the bottom edge for horizontal scrolling.

Two mouse buttons are located just below the pad as an optional alternative to tapping. One can switch the left-and-right mouse button functions, or set the touchpad so that pressing both buttons simultaneously acts as a third mouse button.

Special USB touchpad clips are also available to mount the touchpad over the number keys, for example, or over an unused portion of the F-keys. Two L-shaped clips attach to the underside of the touchpad with feet extending and spaced appropriately to straddle a row of keys. The touchpad can be moved freely from one row of keys to another.
