How to force the dock magnifcation in OS X Lion

In Mac OS X, I keep the dock on the left side of the screen with magnification turned off. I find it distracting to have the icons magnifying as I scroll through them.

However, I just found by chance that if you hold down Shift-Control (⌃⇧) while hovering over the icons in the dock, you can force magnification.

I love finding little things like that.
