Welcome to Tech Talk How does a mouse work? Turn an old mouse over and you’ll see a small ball underneath. As the ball travels over the mouse pad, little light sensors inside the mouse measure the change in direction. A simple two-button mouse is efficient. Left mouse button for action. Right mouse button for options.   Here is a three-button model. What’s the middle button for? With a flick of your finger, you can scroll up and down a Window.
