Show the Dock in Full Screen Apps in Mac OS X Lion

The Dock disappears whenever an app is put into Mac OS X Lion’s full screen mode, but that doesn’t mean you can’t access the Dock if you need it. To show the Dock in a full screen app, swipe twice at the bottom of the screen, the first swipe won’t show anything but the second swipe will draw the Dock upwards as usual.
Regardless of Dock auto-hide settings this will activate.
This feature is exclusive to versions of OS X that have full screen app mode, which was introduced in OS X 10.7 and continues in OS X 10.8 Mountain Lion and later.

Swiping won’t work for me on Mac Pro using Magic Mouse. However, if I move mouse cursor to the bottom of the screen and continue pushing it down (as if I would want it to go bellow the screen), the menu appears.
Munas is correct it is never a swipe, on a mouse or trackpad just move your mouse to the bottom of the screen then move it down a bit more.
useless.
It’s a one finger swipe. Twice. Works fine on my Macbook Pro trackpad.
All methods described above won’t work on my MBA.
With Safari it continues to scroll down the page.
Other time it works casually…
Nick’s trick seems to work at me!
The cursor needs to be pushed into the edge where the dock would appear. So if your dock is on the left, the cursor has to be pushed into the left edge of the screen.

Nick has it right for iMac and magic mouse. Not tried on my MacBook and trackpad yet
