Think the OP is asking if there's a way to bind "empty hands" that you can press/click to unequip whatever you're holding instead of having to use the keys you have the held items bound to.
I don't think there is such a thing.
Yes that is what I am asking.
Press the hot key of the weapon you are already holding and viola, empty hands.
The problem is that I don't have any weapons to do it since my charecter is a pure mage. The only weapon that I use is conjured swords.
I would like to somehow manage to go unarm without having to go into my inventory to activate a weapon (which I don't have) just to unactivate it to go on fist mode.
