An invisible button can get all the button events, but has no up, over, or down state, only a hit area. This means that your button is invisible to the user, but can still do something when they pass the mouse over the hit area, which is also called as the "hotspot".

In flash you can use the invisible button for creating a "dragable area".
1. Open a new movie and create a button symbol. Insert nothing for the on, over, and down state just define your hit area with a filled square or circle.
2. Next, go back to your main timeline, open your library and drag an instance of your button onto the stage, the button will appear as a semi-transparent cyan shape, with the same size as the hit area you have defined in your button.
3. You can put your invisible button on top of something else and then select your invisible button and add the action script from the below, then you are able to move something around. For example, you can make have dragable windows which you can open, close, and move them around.
