I have been trying this with every release of the Mac OS since System 8.0. Apple originally promised this in Copland, the ability to UNDO a misplaced file in Finder. If you accidentally place a file or folder in the wrong place, you can press (or select) UNDO and it will go back to the original location. If you really wanted to move it and you just pressed UNDO, you can just press UNDO again and it will REDO the previous action. You can also copy and paste items in Finder. Very cool and Iim glad itis finally here.
