bulk deleting items in finder, can't press "return" to confirm on dialog?

[clay]

Moved a bunch of files to trash in Finder. The above dialog pops up. Hit enter/return on keyboard. Nothing happens. Move hand to mouse and click on the "Delete" button and it works.

I know we're headed to iOS land on the Mac, but why remove the return/enter key as a way to approve/dismiss default system dialog boxes? Am I missing something here?
