This document provides instructions for adding interactivity to presentations by creating buttons. It explains the four button states - up, over, down, hit - and how to animate the different states. Readers are guided through the steps to create a button symbol, insert keyframes for the different states, and animate the over and down states with different drawings or images that will be displayed on roll over or click. The overall goal is to create an interactive picture that has movement triggered by viewer interaction using the mouse.
