When spanbased selection is chosen Flash treats frames as part of a frame span which means all of the frames adjacent to a keyframe are selected as a unit. You can accomplish the same tasks in either mode and you can switch between the two depending upon the task at hand.

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 animation in the Timeline. Clear Keyframes Click on the frame to select it or click and drag to select a range of frames. Click the Modify menu point to Timeline and then click Clear Keyframe. Flash converts the keyframe back into a regular frame. TIMESAVER Press Shift F6 to clear
