How to change the wall privacy settings on the new Facebook type of settings?

[noone]

How do you change the options so when you post a comment or a video on a friend's wall it doesn't show up on the live news feed on the homepage? Before it was possible, by going to the applications settings and there were boxes asking you what posts you wanted to share with people and which ones you didn't. (such as wall posts, notes, groups, etc)
Does anyone know how to find that option in the new set of settings??

I've searched EVERYWHERE for the settings that can change this. It's so annoying. But I don't think that they have that option anymore. All you can do is remove each post off of your Wall. Yes, it's so stupid. But if you do happen to find these settings to change it, let me know!
