The Video Clipboard is a special window used as a convenient place
to manage video clips created during an editing session.
Each time you press the Copy button, a new clip is added to the
Video Clipboard window.
A clip in the Video Clipboard can be opened as a new Editor by
either double-click on it or drag-and-drop it into the client area
of the main window.
You can also drag-and-drop a clip on an Editor window to add an insertion.
The Video Clipboard will be saved when you quit the application and be
restored when you restart the software later. However, it may take more
than a few seconds to load a long list.
