Sure you can hotkey the left hand skills but you won't be able to use the scroll wheel to change the left side skill. And no, you are correct, you can't add skills to the left side that are not there already.Backdoor Bandit said:What you can do is change the configuration for your skills. All you need to do is place your cursor over a skill and press "fX" (x being a number between 1-8).
That config. is then saved.
