The key bind for "Open Spell Wheel" doesn't open the spell wheel. Everything else in the mod seems to work perfectly except for this, and it's a pretty major feature.

I have the same issue, and also tried to change the key to a regular keyboard key and it still doesn't work.

I'm also having this issue, every time I press the key my default Windows cursor briefly appears and nothing else happens. (ATM9 0.3.2)

Edit: I fixed my issue. Apparently in the Baubles menu, the spellbook is able to be put in both the Curio slots and the Spellbook slots, even though spellbooks cannot be used from the Curio slot. When both slots are empty, Shift+M1 from inventory or M2 from hand will prioritize the Curio slot.
