So, when you open the game from the folder it has the window that pops up, you wanna go ahead and click input, find crouch, and click on the input button untill its blue, then you want to bind it to whatever you want, (i use right mouse)
to preform ths bug, you want to hold ctrl (origional crouch bind) then you want to spam the other bind you made, if you do this like i said, this is what you will end up with.
