In Flash movies, it is very common to repeat motion. For example, if you have a series of text chunks that will all slide in performing the same fade in, there is no need to create the motion several times. If you create one motion, it is easy to repeat it for the other objects, therefore making sure they match.
Try it with us by opening AdvancedAnimation/demos/Animation1.fla. Scrub the timeline to see what is provided. Notice that there are a number of words waiting to slide in from the left side of the screen. The word "run" is already animated. Let's repeat that motion for the other words.
We will work on this file further in the next section.
