If you really can't find a switch, you can always use the [ or ] keys to "teleport" to the quest locations of the dungeon.
Only if you add a line in the Z.cfg that reads "cheatmode 1" (without quotations, obviously.)
I just used that trick before. Stuck in dungeon, trying to kill an atronach, I teleported around the dungeon (it's not exact science) until I found it.
Funny story. The atronach was inside a steel cage. Surrounded by saber tooth tigers. So when I teleported, I teleported
inside the atronach. I had to swing my sword madly until i got the message about it not wanting to go back to the mage guild and then had to use my anchor/teleport magic spell to exit the dungeon before the tigers ripped me to shreds.
Be careful with that cheat. Make sure you save before doing it.
