A lot of people have been asking for a way of crouching to gain speed without having to pop. Now you can also crouch if you hold the left thumbstick up or hold the Up Arrow on the keyboard.
I also rearranged the keyboard grabs a bit (A/S and F/V needed to be switched) and added the keyboard buttons for shifties.
Left CTRL and left Shift to shifty. (The animations for shifties suck right now which is why I didn't put them there at first.)
