to turn arrows[or anything for that matter] on "auto" hold down the hotkey(s) for whatever it is you want to be auto'ed. then while still holding the hotkey(s) click outside the game box [like the white bg of the site]. this should keep your things on auto. to turn it off just click back into game box and press the hotkey for whichever you want to turn off
