To convert a keyframe to a frame, select the keyframe and select Edit > 
Timeline > Clear Keyframe, or right-click (Windows) or Control-click 
(Macintosh) the keyframe and select Clear Keyframe from the context 
menu. The Stage contents of the cleared keyframe and all frames up 
to the subsequent keyframe are replaced with the Stage contents of the 
frame preceding the cleared keyframe.
To change the length of a tweened sequence, drag the beginning or 
ending keyframe left or right. To change the length of a frame-by-frame 
animation sequence, see “Creating frame-by-frame animations” in 
Using Flash
To add an item from the library to the current keyframe, drag the item 
from the Library panel onto the Stage. 
Using layers
Layers are like transparent sheets of acetate stacked on top of each other on 
the Stage. Layers help you organize the artwork in your document. You can 
draw and edit objects on one layer without affecting objects on another 
layer. Where there is nothing on a layer, you can see through it to the layers 
below. 
To draw, paint, or otherwise modify a layer or folder, you 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 new Flash document, it contains only one layer. You 
can add more layers to organize the artwork, animation, and other 
elements in your document. 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. You can also hide, lock, or rearrange layers.
