I say give him the one you would use yourself.

menu * {
-
IRCManager:dialog $iif($dialog(ircmanager),-ev,-md) ircmanager ircmanager
-
}

I used * as an example to show that you can use it to select all menus since LucSatise already showed how to combine more than one menu name. The other difference is the $iif that checks if the dialog is already open and brings it brings it to the foreground if it is and opens it if not.
