Usage of the "-que" Enclitic?

Is the “-que” enclitic commonly used for anything except joining noun lists? The reason I ask is that in D’Ooge (and Wheelock, IIRC) I don’t recall seeing any other use for it. E.g., Curo feminae liberique.

But in Lingua Latina, Hans Orberg uses “-que” to join sentence clauses. I was wondering if anyone here could provide some guidance on how to best use this little caboose.
