Use the timeline to define the content of your movie according to time.
Each frame has a number. You can see the frame-numbers on top of the timeline.
Frames represents a point in time where you can change the movie.
(In a classical movie a frame could be compared to the single pictures).

Keyframes is a special kind of frames. Flash does not store objects in every frame. You will note that if you move an object in a specific frame it will usually also have moved in the frames next to it.
This is because Flash only stores objects in keyframes. All frames positioned between two keyframes are similar.
They all have the same content positioned completely equally.

In keyframes you can change the content of frames without automatic changing the content of the preceeding frames.It is also on keyframes you add tweenings when you want objects to move from the position in one keyframe to the position in the following keyframe.

To turn a frame into a keyframe you first need to activate the frame by clicking it in the timeline. Then you press F6 (or chooses Insert > Keyframe in the menu) to make it a keyframe.

The rows in the timeline indicates different layers. These helps you to organize your work.
Content of the top layer is placed in front of the layer below.

If you want to tween an object, the object must have its own layer. You can not tween objects placed on layers containing other objects.
