When the clipboard contains layer data, the Paste menu item is only enabled when the clipboard contains data for the current plan's layer. The contents of the layer data cannot be viewed directly, but the enabled Paste menu item is an indication that the clipboard contains data from the current layer.

The layer clipboard data is stored in the system clipboard selection. This means that the layer clipboard data is cleared any time another Copy operation is performed, by Concept or by any other application on the system. The selection is also lost if the system is shut down or restarted.
