If you have multiple hard drives set up on your Mac, you may find yourself wishing to move a file (or files) from one drive to another. This generally requires you to copy the file(s) by dragging it to the destination drive, then going back and deleting the file from its original location so you don’t have duplicate copies on your hard drives. Rather than doing that, try holding down the Command key while dragging it to the new location. Your file will be “moved” instead of copied, releasing you from the need to go back and delete the original.
I tried this one of the newer apple keyboard but doesn’t appear to work.
Odd. It shouldn’t matter what keyboard you have, since it’s an OS (software) shortcut.
