great use for the google toolbar

As mentioned in a previous post, I have been projecting song lyrics for church from the laptop. Well I also have the song lyrics on the desktop but unfortunately each song has the filename starting with the number of the song, followed by the book, followed by the title. This is a nightmare to find in explorer when someone says "lets sing 'morning has broken' " as you have to either scan the 500+ ppt files or use the sloooooow search in explorer.
Enter the google desktop. As it now indexes the files, you fire up google (or if smart have the desktop page open already), type in the song title or the words you can remember and instantly you have the results (and in this case we don't have morning has broken typed up into powerpoint!)
