In the Minecraft world, teleportation has been available on SMP servers using other players as reference points. You can teleport halfway across the world to Mr Bojangles no problem. But in single player, teleportation has not been an option.
But that’s all changed with an online tool that enables teleportation by loading a Minecraft world and moving your toon’s place in it. It’s called ‘Lose Me’, which should go a long way towards not inspiring your confidence.
