One Button Modifier Macro for Chakra Stances:
/cast [mod:alt] Chakra: Chastise; [mod:shift] Chakra: Serenity; Chakra: Sanctuary
Can reorganize them however you like, just so the spacing and scripting is exactly the same. As it currently reads, Alt+keybind will put you in Smites, Shift+keybind will put you in Single Target, keybind will put you in AOE.
This little puppy will make your day by preventing multiple action bar slots, dropdowns, or clicking being required.
