Oh, okay, I was thinking of inner quotes already in the post.
I’ve never clicked a button. I just type [noparse][/noparse] around what I’m hiding.
Oh my Og, thank you! I’ve never been able to figure our how to do that!

Actually, you also have to remember to close the spoiler, and actually close the spoiler, instead of closing a quote.
