How can I connect multiple inputs in Grasshopper?

I know this is probably a stupid question but I can’t find a solution anywhere:

I’ve been following tutorials in Grasshopper that call for multiple connections to the same input node. Whenever I try to connect these, it will kick out the other inputs. For example, when I try to use Brep Join, it only lets me connect one brep. I haven’t done anything different than the tutorials I’m watching so I’m wondering if this is an issue with my settings.

Hold Shift while dragging additional wires.

Just remember that the order in which you connect the wires determines the order of the resulting data. Sometimes this doesn’t matter. When it does, use a Merge component to make the order clear.
