MW I just bought a house that has a light switch that controls nothing! How
MW do I trace what this switch is supposed to do without ripping out walls to
MW trace the wiring? Suggestions? (now... be nice) ;-)

Maybe it does do nothing! When we had the addition done here a couple
of summers ago they undid the wiring for a spotlight on the back of
the house (the spotlight was moved and connected to a new switch).
The old switch is still there, with wiring into the ceiling zig-zagged
in between the joists so if we ever wanted to add some accent lights
against the wall we could.

As far as tracing I've used a signal injector (for audio electronics
troubleshooting) and an AM radio. Make certain the switch is off so
no power when the injector's probe is connected to the wire. (And
yes, I'm aware not everyone happens to have a signal injector! g)
