Dragon sprint and dragon leap
Basically http://www.youtube.com/watch?v=GF-Ch2BafQw, but each leap is a single shout, but the leap shout recharges fairly quickly (10-20 seconds).
Also, when in mid air you glide down to safety instead of just falling, kind of mimicking the way dragons glide through the air when they fly, except you can only go down.
And dragon sprint means you can just run incredibly fast for about 10 seconds, but takes a long time to recharge, and you can attack and jump while running too.
Udig?
