Flick to close running apps?

[SuperBubu]

Hi,

I am new to Android and GN2 and have seen videos where the user is in the settings menu and can close running apps out with a flicking motion.....I have gone through my settings menu, but have not come across this option. I am using the US AT&T version of the phone. So far the only option I see is going into Application Management from within settings and going into each individual app to 'force close' the app which always gives a visual warning.

Was I wrong to have seen the ability to flick close apps from the settings menu?

Long press the home button and it will bring up your recently used apps list. You can swipe away from there.
