If you time it correctly, you can use the numpad keys to move almost indefinitely. While this has been convenient for testing mods and such, I thought I should say something about it. It's like if you hit the key just as your unit enters the new square, he'll jump to the next. You can keep doing this. I had explored half a map in about 8 turns (with a unit that has a move stat of 1.2 or something like that). You can do it on the cloth map too, although its more difficult to get the timing right.
