How to make auto-chat work for all players (Area) instead of Group chat?

Title says it all, I want to figure out how to make my auto-chats go for all players in the area instead of group chat.

use /a in the autochat that will change to area

Just be careful with area based autochats, some of the triggers go off way too frequently, and there are a lot of irritating players who put cut-ins on their spammy autochats (I have blocklisted several of them).

But for the channel settings:

/a = Area (Normal chat)

/p = Party chat

/t = Team (Alliance chat)
