Symbols

A symbol is a graphic, button or movie clip that you create once and then can reuse throughout your movie from the Library.

• Graphic symbols: are used for static images and to create reusable objects for your movie or animation that are tied to a timeline.
• Button symbols: create interactive buttons in the movie that respond to mouse clicks, rollovers or other actions.
• Movie clip symbols: create reusable pieces of animation. Movie clips play in their own timeline independent of the main movie's timeline.

Using symbols dramatically reduces the file size of your movie, by saving several instances of a symbol less storage space is required than saving a full description of the element for each occurrence.
