"Command F" (Mac) or "Control F" (Windows) brings up a search box in the upper righthand corner of any webpage to search within that page for any letter, word, or phrase. If you are doing some preliminary research on a topic, this is a handy tool to quickly see if the page has enough information on your topic to do you any good without having to read the whole page.
For example, if I want information on turkey calls, and I have pulled up a hunting page on the NWTF site, I can hit Command F and search "calls". It found three matches, one of which looks like a great link to a page that will do me more good.
Play around with this a little. It will help you hone in on the information you need more quickly.
