i cant find anything in the config file related to touchpad or natural scrolling, arent wm supposed to have touchpad support
use xinput
xinput list # << to list the devices
#Then make a note of the ID of mouse(or touchpad if on laptop)
xinput list-props {ID}
#Then use:
xinput set-prop 12 313 1 # <<< As an example (mine)
My ID is 12, the property is 313, 1 = on, 0 = off.
Natural scrolling was designed by the devil 
thats complicated
