Selecting while playing
                                          

Sometimes, you’d like to listen to a movie’s
sound track while you are selecting so that
you can listen for a certain sound or word.

To select while playing a movie: 
1. Move to the part of the movie where you
      want to begin selecting.
2. Hold down the shift key.
3. Click the Play Button

         The movie begins playing and the 
         selection follows the thumb as it plays.

4. When the desired point is reached, lift the
      shift key or stop the movie.
