@apodsim Dan is correct, as is @RTCool. I am definitely one of those who is maddened by the lack of a dedicated Copy “tool” (pace Dan!). And who maddens those who aren’t.
People often confuse the software-dedicated copy/move tool with the operating system Copy and Paste that is more universal. But you are right that those universal commands can be helpful in SU too, for moving components between drawings, etc. It just isn’t the subject of this thread.
