I miss/need a critical gesture from Snow Leopard...

[emilioestevez]

Who remembers the native 4-finger gesture swipe up that moves all your windows to the side and shows you the desktop?

I couldn't live without it, but for the life of me I can't figure out how to perform this gesture/action within Yosemite.

Help?
