The "E" key is allways bound to "cycling forward" when using the AH-little bird.
I wanted to rebind the "turn left and right" keys to "q and e" and found out that this is not possible since there will allways be the "cycling forward" function bound to "e".
This is probably a simple typing error somewhere in the config at yours.
But it doesnt need to be in the final product;)
