Copy + Paste are 2 actions to move data to/from the system clipboard (as principle you can share the data with any other compatible third-party program or any other instance of the same application). Ctrl+Drag is an action to clone an object inside the current instance of the application. The final result may appears to be the same (provided you paste what you've copied) but the process and what you can do is different. In SMath: - copy/paste is performed serializing and deserializing the data via ToXml/FromXml. Since the data is passed by parsing values contained in the xml string stored in the clipboard, new objects are not linked to the original. - Ctrl+Drag is driven by Clone(). Here you have to deal with .NET Framework; some types are passed by reference, other by values (see here and here). Depending on how it is developed the region, you may need that some values passed by reference were passed by values; in this case you have to make a deep copy of the objects, implementing your own Clone() in your classes and casting the objects where it is needed to break the references.
