True that.
I don't know it's probably old news, but if you jump and hit ctrl+E, you'll do a spin attack.
Now, if your timing is right, you can do this spin attack again and again pretty much, it makes you travel so fast, no run speed mod needed!
Also can be used to descend, if there's no wall to run on, or you're just all crazy.
I managed to do like what.. 15-20 of those in a row, but I couldn't feel my pinky for a short period of time after
