This is an anti-gravity hack for 2.1.3, working on live servers.
Press Shift+F11 to enable the hack, Now when you jump or walk off a cliff you will float. Shift+F12 disables.
This is good for getting to places slightly out of reach.
NOTE: While floating the game will consider you falling. So if you float across a canyon and land safely on the other side you will still die of fall damage.
