This is what Windows Explorer does when you cut a file, except it does also place it on the clipboard.

>What if you want the original semantics of cut? Ghost cut makes that two keys rather than one: copy to clipboard (control-C or command-C) followed by Backspace to remove it from the original document. I so rarely use cut without paste, that this is a clear win for me.

This is just as "broken" as the existing functionality, just in a way that the author prefers. It's a neat idea though, I like it, makes you wonder what would have happened in other apps if cut/paste was never developed as a system-wide, cross-app capability.
