G9 manual shooting with canon housing

[walkerl]

I'm hopefully missing something very simple, but I can't seem to shoot manual with my canon housing. On land, you have to use the control wheel to shoot manual, and there isn't a control for this on the housing. So how do you change the settings.

Thanks for any help, and again, I hope this turns out to be a really dumb question.

Aloha,
Walker

Nevermind. A quick google search and I found out about the S button on the top left.
