Sherlock
If you click the Sherlock Holmes hat you see in the Dock, you'll get the application shown below, called Sherlock. Sherlock is the tool you use to find any file on your hard disk, or to find things on the Internet like old friends, shopping bargains, definitions of strange words, research articles, entertainment, and more. See Chapter 24 for all the details.
Click any of the other "channels" to log on to the Internet (providing your connection is set up first) and find various sorts of information.
