On Windows, pressing “Enter” on the deletion confirmation dialog cancels the deletion, which is different from the behavior of the Windows Shell. This would be useful because it’s much faster to be able to delete items purely from the keyboard.
I’d like this on Macs too, though I do understand that being click-only serves to avoid accidental deletion. Perhaps it should need Ctrl/Cmd and Delete.
Add my vote to this as well. I want the enter key to confirm the delete and the escape key to cancel it. Anything other than this is poor UX as this is how every other software works.
Alternatively, provide a setting to avoid seeing the delete confirmation entirely, at least on a drive where the deleted file goes to the recycle bin.
