Option + Com + Click to Select object?

Am I crazy? I used to use a mac keyboard shortcut Option + Command + Click to snap a selection around an object on a layer. It was useful if I had lots of seperate images with negative space around them (e.g. confetti) and I wanted to select broadly with a square marquee, and then use opt + Com + Click to snap a clean selection around the edges.

Am I the only who used to used this shortcut? It's not avaliable in my current version of Photoshop? I don't know what this short cut is called so I'm having trouble resetting the command or finding information about it. 

TIA
