Can't Delete Items In Editor Using Delete Key

I just got the engine 3.7.16 installed on my iMac and noticed that in the editor, I cannot delete cards from a deck using the delete key as formerly. I have to right-click on individual cards and select from the popup menu. This makes many module design chores extraordinary tedious! Is there a way to reinstate the functionality of the Delete button?

Thanks!

I found it! The key is now CMD-Delete on iMac.
