Copy/Paste Tools
The copy/paste buffer currently stores a set of temporary F-Curves containing only the keyframes that were selected in each of the original F-Curves. All pasted frames are offset by the same amount. This is calculated as the difference in the times of the current frame and the `first keyframe` (i.e. the earliest one in all channels). The earliest frame is calculated per copy operation.
