Answer 2

The timeline is one of the most important toolbars in Flash. On a timeline you have frames and keyframes. A frame is simply an intermediary between keyframes, there is no change in the amount of objects on the stage during a normal frame. Keyframes are major changes in the state of the stage. You use them to add a new object or end/begin an animation.

Keyframes are marked by small squares with a black dot in them. Blank keyframes are marked by a square with an empty dot. You can insert a frame with F5, a blank keyframe with F7, and a non-blank keyframe with F6. (You can also insert frames and keyframes from the contextual menu, which can be accessed by right-clicking on the timeline
