As of EE2

1) G no longer gives you the ability to fly. Instead, pressing jump twice (like in creative mode) with SWRG anywhere on the inventory hotbar (even non-active slot) will activate the SWRG's flying ability. Pressing jump twice while flying will disable flying, and flying mode on the ring. Flight will also be disabled as the player lands.

As of v5.x.x:

1) Left clicking fires a projectile, which launches mobs for 1 redstone dust, unless it's raining. If it's raining, (and you're outside) the projectile will hit them with lightning for 2 glowstone dust. If it's a thunderstorm, it will hit them with 2 or 3 bolts for the same price. When fired directly into the air, the projectile will transform any rainstorm into a thunderstorm for 1 redstone dust.

2) When activated with G, you will be able to fly. Pressing jump twice (like in creative mode) begins the flight mode or ends it. Pressing sneak descends. It must remain on your hotbar or you will fall. While on your hotbar, you are immune to fall damage.

3) When activated with C, a different effect will activate, creating a barrier around the player, in the shape of an 11x11x11 cube. It will repel mobs and enemy projectiles.

Both abilities, can be activated independently of one another, and the ring will display a color blue, red, or purple to indicate flying, barrier, or both, respectively. The ring will consume 1 redstone dust per 10 seconds, or a Klein Star point per 10 seconds (40 seconds for glowstone dust, 2 minutes for gunpowder, 2 minutes 40 seconds for Alchemical coal/glowstone blocks, and over twenty full minutes for mobius fuel) If both abilities are active the time is cut in half.

It appears that creating a map while using the fly ability of the ring will always create map_0, regardless of your location.
