[HELP]Switch to target Auto Attack?

Hey for some reason whenever i try to auto attack by using this key ~ it won't work. So i was wondering if there was some way i could change the key to Auto attack / switch target. Which is normally this ~
Thanks will be given :D

try ^

I think it is worth pointing out the fact that you need to manually attack the first time, and then you press that button (before number 1) and then you will start auto attacking.

No as in the ~ button that switches target so i kill a target then i go to the next target like that or as a viewer ... that button doesn't work for me.
