Is there a shortcut to change snapping type? I really like the "Pie-menus" addon, it allows me to change my editing setting really quickly. It's awesome. 
I also love snapping, it's so snappy and fun, but I need a better way to change the snapping type (i.e. vertex, increment, or face) than this:



I think a hotkey for toggling snapping type and pie menus would work great together, in fact, it's probably already a thing. So what is the key shortcut?
There is. Ctrl + Shift + Tab. In addition, you can also toggle snapping altogether from there.



You could literally have hovered over it :P
