How to Create an invisible button in Flash

Ever wondered about when your mouse moves over a website and some animation plays? Well, that's an invisible button. To create one, first type some text in Flash. Then create a new layer, draw some basic shape, and convert it to a button. Then double-click and create a new keyframe on hit. Scale the shape according to the size of the text. Now, when one moves the cursor on the text,the cursor becomes active. It really helps for some animation with greeting cards.
