I happens to me regularly. I use the technique to find information from web pages. Ask a specific question, open all the finds in the search engine PR each page and know if the data/information I am looking for are on the page.
I also soved a computer problem by obtaining some information about dos commands to bypass my windows operating system and save some important data. Took me 3 minutes to find the informatin by Photoreading the book (knew I PRed it while flipping pages) just went back to the page and knew exactly what I needed to do.
