Do you expect me to watch the entire 20 minute video to find the segment you are referring to? This is your problem, not mine. Link to specific segment.
Also, I will go back to my point. You are not solving a real problem. Saying “left trigger + face button top = F10” does not help, this is not a real problem. What does F10 do? Does it execute a function? Then call that function using the technique that was demonstrated here earlier. You already have all the answers you seek. Just follow the advice you’ve been given.
