Probably a stupidly simple thing but, as the title says. Randomly I'll copy a sprite (such as an SE or L+) and find that it sometimes retains whatever tags or EXTRA or whatnot that I originally applied to it. Is there some specific key combination to use when copying to do this? It'd be incredibly helpfull, especially when working with some Polymer lights, but I can't seem to find any mention of this in any command listings and such. Any ideas?
