Is the skill bar configurable, or do you have to use number keys for skills?

I looked under controls and my only options are "general", and if it is done through the hot bar itself, then I must be dumb.

Edit: Still not sure if you are able to set custom keybinds for skills. I don't like using 1-9,0 for my skills. Maybe it can be done through editing game files?
