Trackball mice can give computer users with limited desk space an easy means of controlling the cursor. Rather than having the computer mouse slide across a mousepad, the trackball mouse stays stationary. You’ll roll the trackball on the top of the mouse with your thumb or fingers to move the cursor across the screen. Many trackball mice are finger-operated models. This means the trackball is on the top-middle of the mouse. You’ll operate the trackball with your index or middle finger. This design uses a large-sized trackball, which is helpful for precise control. Another option is the thumb-operated trackball mouse. With this design, the trackball will be on the left side of the mouse. You’ll use your right thumb to operate the ball.
