I take advantage of WidgetLocker's timeout override feature.
I set WidgetLocker to 10 secs to TO (10 secs the fastest available)
BUT on my phone my default TO is 1 minute.
So whenever I want the phone screen to power off quickly (I gesture as I use LPP) to activate the Widget Locker screen and then 10 secs later the phone screen goes off. Saves some wear/tear on the power button.
But once I'm back at my regular homescreen, my 1 minute TO default kicks back in.
Sometimes you can also wake the phone with the Volume rocker, but not always. I think it depends on how long the phone's been sleeping after activating WidgetLocker that allows the Volume rocker to wake the phone.
