That menu command and its keyboard shortcut, Shift-F6, will turn the keyframe into a regular frame instead of deleting it. If you want to delete a selected keyframe, don't choose Modify > Timeline > Clear Keyframe.Then select the newly inserted frame and press F6 to turn it from a regular frame to a keyframe. The second of the two keyframes, and everything beyond it, moves one frame to the right. (All that happens is that the playhead moves to the next keyframe there are no changes at all in the Timeline.) Instead, select the first of the two keyframes and press F5 to insert a regular frame after it. If you want to insert a new keyframe between two existing keyframes, don't select one of the keyframes and press F6.(Note that any hints dealing with F6 apply to F7 as well.) Instead, here are some general hints to help you deal with the less-intuitive aspects of working in the Timeline.

We won't try to give you an exhaustive list of menu commands and keyboard shortcuts for editing you can get that information from the Help menu. You may want to make parts of it longer or shorter, change its position in the Timeline, add more action to it, or take some action away. Once you've created and previewed an animated sequence, you'll almost always decide to go back and modify it.
