All I want is a simple way to bind a set of spells or weapons to one hotkey, ideally something compatible with SkyUI and without many other features.

If I could just do something like go into favorites, put the two spells I want on L/R MB, bind them to one key, that would be great.

Anyone know of a mod close to this?

Sounds exactly like the Groups feature of the new favorites menu added to SkyUI 4.0

There are some more over there.

I want to bind them to 1-9 keys, and use them out of the favorites menu. I know I've tried a few of those already in the past and had issues.

I want to simply go into my favorites menu, put LMB/RMB onto two spells, and assign those to hotkeys 1-9. Might be impossible due to the game having decided it wants 1-9 for itself alone though. :/
