Well the file would go in the Trash, so if you pressed delete accidentally it's not a disaster. I use Presbutan so pressing delete on its own works, and pressing enter opens the file, instead of having to use Command-O.

Command-Delete also makes sense as it follows the convention in the Finder / Desktop). Command-Z works to reverse both operations.
