I was very confused until I realized that quickslots has its own section in the options screen. Which explains why I couldn't find the controls in the UI section.
The other thing that has me wondering is in the section for deeds (*** incorrect terminology alert ***), I've noticed that you can kill a gadzillion orcs in CloudCuckooLand to get 5 TP and some nearly useless potential buff, or you can hit the Accelerate button.
I don't recall seeing the Accelerate button before. What exactly is it for (yes, I know, the slothful), and what happens exactly if I hit it? And will my inner Cotton Mather go berserk if he catches me doing it?
