How to get to the Action Flow

I know this is probably the most basic question posted on here, but I'm working my way through the courses and I can not for the life of me remember or figure out how to get to the Action Flow for a particular screen. I know that it has to be right in front of my face because all the documentation I can find on the Action flow simply starts off with "1. Open the Action Flow." 

Thanks in advance and please be kind, I do realize this is a very dumb question.
