The page says I can config the toggle button myself. But there is nowhere to config it..? XD Like? What am I missing here..? There are no mod setting for it. There is not setting in controls for it.. The only thing you can set when in game is what signal get pushed. But no way to set a toggle button for this mod.....

I found it. It's in the normal setting under debug as Toggle Entity. For anyone else who might be having issues figuring this out. Not a lot of explanation on this page or the mod itself.
