Use IJKL to move the camera and use UO to zoom in or out.
I was gonna make a second version of "Gravitron Sandbox" by having multiple planets affect each other with gravity, and then I realized that the "repeat" feature doesn't go through everything; there's an interval between repeats and it gets irritating when it happens. Might do that in Lua, I guess. So have fun with this. Silly camera mode.
