When you copy/paste it is a phantom copy like when you Alt-Drag an event (arrow cursor). There is a + added to the event’s name.
You can turn a phantom copy into a real copy with the option “Clone Phantom sequence”.
When you Ctrl-Drag an event the data are duplicated (plus cursor), for an audio event it creates a new wave file. There is a number added to the events’ name.
I know it because I always need real copies of enveloppes but phantom copies of sounds and I often make the mistake with the shortcuts !
