In WoD, Blizzard added the ZoneAbilityFrame that has the special button for your garrison ability
or whichever zone ability you chose for the other Draenor zones.
In BfA, this same button activates things like the sanity orb for Horrific Visions. The problem is
that you can't bind it to a key, and you can't make a /click macro for it.
This addon creates a hidden button, called myZA, that points at the ZoneAbilityFrame.SpellButton.
You can set a keybind for myZA, or you can make a macro with /click myZA
Shadowlands introduced multiple zone abilities during the leveling process, so the addon has been
updated to also support /click myZA2 and /click myZA3.
There are also new bindings available in the "Other" section for each zone ability.
