What kind of action is this?

So I’m following a blueprint tutorial for a simple inventory system, and I can’t seem to figure out what this action is inside a macro within the base inventory blueprint.
Any ideas?

I circled what I don’t recognize in red.

Looks like its getting the variable “stackable” from the object.

Oh, okay. How would I pull that var from that blueprint to this one?

I actually figured it out. I pulled the wire from Item In and checked Context Sensitive and searched for stackable. Picked the Get Stackable and got what I needed.
