OTOH, if you mean copy and paste of a single point (like a position of a PIP) like you can do in Avid, sorry to say FCP can’t do it.
Its my biggest complaint about the FCP motion tab.
To be able to copy a given position at a certain point in the effect, with all aspects of that position (size, shadow, crop, vertical, horizontal, etc.) and then paste it on another point in the effect is a very important feature… sadly missing.
