Flash button

 I added a button by drawing a rectangle  clicking it so it was selected pressing f8 and choosing button. I then double clicked it which made the back ground pale out.

where the key frames usefully are you will see the up over down and hit actions. you can add what you want to happen when it does it , for example the button changing colour when you click it .  You can move it make it change colour or show signs when being hovered and over being clicked .
