Stupid question I know, but what is the button for the quick select menu?

I'm playing on PS3.

Thanks.

Inside the pipboy menu, hold R2 and then use the 4 way digital to assign items/weapons/armor to a specific button. (on the digital pad)

I know that but how do you quick select them when your actually playing?

Press up, down, left, or right (theres also bottom right, top left etc) on your directional pad.

Push the button that you assigned them to?
