Hello.
I’m looking for the Blizzard-provided Console/Chat/Macro Command List.
Is it possible to obtain a verified, comprehensive list of all hidden and useable commands?
To my very best of knowledge we have never actually published an exhaustive list of these commands, and it is somewhat unlikely that this will change in the future.
It should also be noted that the very vast majority of console-commands are meant for emergency use only, and have the potential of seriously impacting the game interface if applied even slightly incorrectly (e.g., a small copy/paste error or typo could change the location of an UI element in a way that’d literally push it out of viewable space on the screen). There is however an official forum specifically dedicated for the discussion of macros/scripts/UI-mods, so that may be your best port of call if looking for more information.
