I got this committed, but forgot to note your name in the changelog when I did. I will try to remember to add it in the next update I do.
I was able to verify the /zone opcode worked, but I have no idea what the petition que one does or is for. I don't see a command for petition queue, and the only thing I see tied to the "G" key on Titanium by default is ALT+G for guild management. Either way, I added the petition queue one you posted only because it was previously set to 0x0000 and the one you added did not already exist elsewhere in the conf file. If you can provide more info on what that is actually for, it would be appreciated
