Sell Key on Mac?

I have been searching online trying to figure out what the sell key is for Mac?  Every article I read says to use the backspace/delete key to sell, and while that works on my pc, it sends it to my family inventory.  Is there a key binding to sell on Mac?  Or am I stuck with having to drag each individual item down to the sell box.  (Those stupid gnomes rezzed like 100 packets of seeds)
