It doesn't.
I am interested in the new shortcuts however. The other mod does its work with an item, and it's irritating to have to hunt through your inventory for an item every time you use it. Especially since you can't even make the item return reliably to the hotbar so you have to hunt around in your inventory for it every time you want it.
The picker tool you link seems like maybe it will provide something similar to what I want in the way it lets you move around entities. I've installed it, but haven't tested that aspect yet. And, annoyingly enough, the picker tool does a lot more than I want it to. :-( Some of the things it does feel like cheats.
Thank you for your reply.
