Three or more paths (before Opus 9.1.1.6):
We used to have a kludge here for older versions of Opus which (ab)used a Rename script to cycle three or more paths. That isn't a good way to do things now, and really just complicates matters, so it has been removed. You might find some other threads in the forum that reference the old Rename-script method, so I've left mention of it here to avoid confusion with the newer methods.
You can look up this posts's edit history if you really want to see the old method, but it's not recommended. There are better ways to do it now, either using the commands above, or using proper scripting if you want to do something extra, like in tbone's example below.
