Go to Insert > New Symbol, or press Ctrl+F8.

2

In the Symbol Properties dialog box, enter a name(eg. buttun) for the new button symbol and choose Button as the Behavior option. Flash will then switch to symbol-editing mode. The Timeline header changes to display four consecutive frames labeled Up, Over, Down, and Hit. The first frame Up being a blank keyframe.

3

To create the Up state button image, use the drawing tools, import a graphic, or place an instance of another symbol on the Stage. Here we shall start by drawing a simple circle.

One can use either a movie clip or graphic symbol in a button, but cannot use another button in a button. Use movie clip symbols if you want to create an animated button.

4

Click the second frame, labeled Over, and choose Insert > Keyframe. The button image from the first frame appears on the Stage. Change the color of the button using the paint bucket tool.

5

Change the button color for the Over state. Repeat steps 4 and 5 for the Down frame and the Hit frame.

The Hit frame is not visible on the Stage, but it defines the area of the button that responds when clicked. By default if you do not specify a hit frame, the objects in the Up state are used as the hit frame.

6

When you've finished, choose Edit > Edit Movie, and then drag the button symbol out of the Library to create an instance of it in the movie.
