How do you type where you wan to go in aqw

Like this: /join ballyhoo (or whatever location you want to go to) you can add in a hyphen and random number if you want to go to a particular room for example if I want to join ballyhoo's room but did not want to go into an overly crowded room instead of just /join ballyhoo I'd type it like this /join ballyhoo-58423 or any random number like this.
