This is a very, very simple mod that adds instant teleportation over a short distance. Shift + W A S or D will "blink" your character in that direction 10 spaces. If you want to move farther, I added a "Big jump" with Control + W A S or D that moves you 50 spaces. This was inspired by the Warcraft Mage spell "Blink"

There are no controls or safeguards. You might blink into water, the middle of an item, anything. It hasn't killed me yet (other than blinking into the path of a train), so that's good news. Use at your own risk!
