The third side has an inset portion for placement of the tip of an index finger of either hand. Each of the first and second sides has an aperture. A ball is rotatably mounted in the housing so that the ball is exposed in the first and second apertures. The trackball apparatus is usable in the left or the right hand of a user. First and second buttons, connected to a single electrical circuit, are on the first and second side, respectively, of the housing.
