Igor, Would it be possible to offer Relative and Absolute options when cloning keyframes? If the Relative Option were used then moving the original (Absolute) keyframe would result in all clones moving by the same amount. If the Absolute Option is were chosen then the cloned keyframe would remain in its position regardless of any changes made to the position of the original. Perhaps a refinement would be to be able use Ctrl + Click on a keyframe to change it from a Relative Keyframe to an Absolu
