• To display thumbnails of the content of each frame scaled to fit the Timeline frames, select Preview. This can cause
the apparent content size to vary and requires extra screen space.

smaller than with the Preview option.

About layers

Layers help you organize the artwork in your document. You can draw and edit objects on one layer without affecting
objects on another layer. In areas of the Stage with nothing on a layer, you can see through it to the layers below.
To draw, paint, or otherwise modify a layer or folder, select the layer in the Timeline to make it active. A pencil icon
next to a layer or folder name in the Timeline indicates that the layer or folder is active. Only one layer can be active
at a time (although more than one layer can be selected at a time).
When you create a Flash document, it contains only one layer. To organize the artwork, animation, and other
elements in your document, add more layers. You can also hide, lock, or rearrange layers. The number of layers you
can create is limited only by your computer's memory, and layers do not increase the file size of your published SWF
file. Only the objects you place into layers add to the file size.
