How do I re-bind keyboard button ?

It allow me to bind button when I start a game first time.
But I could not found keyboard setting in option menu.

Your guess is as good as mine. As far as I can tell, you have to bind keys to gamepad buttons, and then you can bind those keys to gameplay functions. Actually doing the bindings is like doing a rubik's cube, because switching through the bindings for any one game function will change the binding of another if you choose a key binding that's already been bound.

I have never seen worse functionality to rebind keys in a game.

You have to switch to display the keyboard buttons, then it will show keyboard prompts (switch button image), though in the rebind keys section it will show the controller buttons for some reason again. It doesn't affect me per se, since I do have a controller, but it would be nice if it actually displayed the keyboard keys for people who do use the keyboard, in the button mapping section.
