In this video by Task Tutorial we learn how to create a simple text effect in Flash. The first step is to create the text you want to use. Then use CTRL-B to break apart and distribute to layers. Now, convert your letters into movie clips using the menu options. Then add key frames and edit Alpha values in all of the letters. Alpha must be 0. Then add motion to the values and at frame 10 add a key frame. And at frame 15 add another key frame. Next use the free transform tool to move the text and create motion. Next edit the alpha values. Finally you can test the movie to make sure it works the way you want it. Using these instructions you can create a simple text effect in flash.
