[[ makes the most sense everything else is dumb
no need to write out /looc thats like 5 characters and inconvenient, why use it when you have a shortcut
.// is 3 characters and open to easy mistakes such as sending a message out in global ooc
[[ 2 characters, there are no other commands that start with [ or any other key in the area, even if you mess it up its still posted in local chat
ill half-accept .// as an alternative for oldheads since im guessing there was no other shortcut in the past and theyve committed it to muscle memory over the years, but /looc is inexcusable
