On a related note: Use BetterTouchTool to re-bind four-finger upward swipe to tile/untile open windows in the frontmost application, and re-bind four-finger side swipe to activate the next/previous open window in the frontmost application. The default actions for those gestures are useless, IMO.
I didn't see him mention Control-L for putting focus on the location bar in Chrome and other web browsers. I use that constantly.
