ptg 224 Chapter 7 Depending on what you are trying to accomplish, you can choose to remove a frame's status as a keyframe or remove the frame entirely. Clearing a keyframe preserves the length of the framespan and the overall duration of the animation on the layer. It simply turns the keyframe back into a regular frame and removes any changes the keyframe contained. Conversely, removing frames deletes the entire frame and shortens the framespan as well as the length of your anima- tion in the Timeline.

You can add or remove content from a keyframe, move keyframes around by simply dragging, or copy and paste keyframes in the same Timeline, across scenes and even other Flash documents. Because keyframes are so versatile, you can con- tinue to fine-tune your animations after they are created. When the playhead is placed on a frame, the content of that frame is displayed on your Stage. Selecting the keyframe in the Timeline selects all of the content on that keyframe on the Stage. Likewise, selecting any of your content on the Stage will select its corresponding keyframe. In this way, you can interactively edit the content in a keyframe or the keyframe's position in the Timeline and know what you are affecting.

It’s important to understand the differ- ence between the normal copy and Paste commands and the copy frames and Paste Frames commands. When you copy and paste frames you are copying the keyframes and in-between frames and the content contained in them. Pasting them preserves the structure and layout. If you select a keyframe and use the normal copy and paste commands A+C and A+V (Mac) or Ctrl+C and Ctrl+V (Win), you are only copying the content contained in that keyframe. You can use drag and drop to copy frames. Press and hold down the Option (Mac) or Alt (Win) key as you drag frames, Flash copies them to a new location. From the Library of Wow! eBook ptg 228 Chapter 7 Flash incorporates the traditional animation technique with its use of keyframe-based animation. Artwork is placed in a keyframe in the Timeline and subsequent keyframes are created to record changes to the artwork. When played consecutively, these minute changes mimic movement as each keyframe describes an altered position or transform effect. Static art that does not change is stored on separate layers and can span the entire animation. In this way, you don't have to redraw the entire frame and you can quickly create complex animations.
