Paste or move a keyframe
If you record a change on a property but decide that you want that change to occur sooner or later on the timeline, you can move the keyframe.
A keyframe from one object cannot be moved to another object.
Moving a compound or object-level keyframe will also move all the child element keyframes.
Select the timeline from the Storyboard picker by clicking Open a Storyboard under Objects and Timeline and then selecting a storyboard.
Right-click the keyframe that you want to move, and then click Cut or Copy.
Move the timeline playhead to the location where you want to paste the keyframe, and then, on the Edit menu, click Paste.
