I would like to second that question...Well, more like, searching for an address when you can only trigger an event one time.
Example: In Pokemon, you can only do events one time. How can you search for an address that could only be encountered once?
Edit 1: I realized I didn't go to the 6th page before replying to the last message on the 5th page -.-
Edit 2: I guess you'll just have to use save states.
