I get the concept... but the actual step by step procedure eludes me.

What I have tried to do in the past is route all instruments that require reverb to a single instance of a reverb plugin. But I must be missing a key step because those instruments never end up having reverb.

Maybe now that RB is 64 bit and I have plenty of ram, it won't matter to put a separate reverb plug on each track that needs it. But I'd rather learn how this is supposed to work so I'm not on my deathbed someday thinking "dang, I never learned how AUX sends work..."
