wasd keys to navigate 2D, o and i keys to move around in 3D space, and j and k keys to move around in 4D space. the h key does absolutely nothing but you can press it if you want the L key also does nothing but if you press it enough times you may type the letter L (scary I know)
Fixed a bug so that you can't make it try to go to universes? hyperlayers? that don't exist (i.e. it won't try to take you to 1 1 1 -1)
