The SFC editor fully supports drag and drop for moving or copying items. To move items, select them and simply drag them to the wished position.
To copy items, you may do the same, and just press the CONTROL key while dragging. It is also possible to drag pieces of charts from a program to another if both are open and visible on the screen.
At any moment while dragging items you can press ESCAPE to cancel the operation.
Alternatively, you can use classical Copy / Cut / Paste commands from the Edit menu. Paste is performed at the current position.
