Macromedia - Give Your Layers A New Look In Flash (5/MX)
Flash makes it easy to change the appearance of your layers and help you organize them according to your own style. First, you need to access the layer Properties dialog box by selecting your layer and choosing Modify > Layer. Here you can change the Outline Color of your layer, have Flash display it as an outline only, or change the height to better fit your content. The latter option is useful when working with audio files, as you can make the layer taller and better see your waveform.
