What is the use case of a "Undo Copy" feature anyway? I can see some cases that I'd want to "Undo Cut" but why do we need another shortcut to delete a file just because it was copied?
For example, if you Control+V-d the files into the wrong folder in windows explorer. I've undoed copies many times this way.
However, the post doesn't mention whether this behavior is present with Ctrl+Z as well. If so, that's even words, because you wouldn't even get to read the action you're about to perform.
