These are all the ini settings if you want to change them.  

For example, to change Crouch to the Z key, just change the value in this string:
ActionMappings=(ActionName=&quot;Crouch&quot;,Key=C,bShift=False,bCtrl=False,bAlt=False)

to this:
ActionMappings=(ActionName=&quot;Crouch&quot;,Key=Z,bShift=False,bCtrl=False,bAlt=False)
