Two ways power searching can help

I recently just finished the Google power searching unit and there are a few things that I learned that can help me. First, I learned that if you hit CTR L+F it brings a search bar up and allows you to search for different words on the page. This would have been great if I had found out a few years ago. This is such a useful tool because it can help out so much when doing research. Now I can search for words on a large website instead of having to scan through it. Second i learned how to search by image. All i have to do is drag the picture from the desktop to the search bar of Google images and it will search the picture for me. Now when need to find where the picture was taken or who took the picture I can just search with the picture. Those are two ways of how power searching with Google helped me.
