Clark P.S. I don't know if the image will embed properly. I will update this accordingly.
P.P.S. Seems like I can't embed it. Definitely more difficult on Android than iOS imo, beginner's luck (':
You can't embed it. That's a forum issue, nothing to do with Android. You have to post the image elsewhere and link it here. Also the forum has a time limit of only 10 minutes for edits.
As for your question, I don't believe there is one sadly. I looked through both navigation sections on the website, but the best I could find is a mention that:
Apps are supposed to avoid implementing conflicting gestures, but have the option to override this gesture if they truly need to get rid of it.
To me, that sounds like there might be apps that could provide a forward function, if I'm not misunderstanding.
EDIT: Maybe it refers to in-app gestures, actually?
