This box exists only to allow you to access this outlying region of the screen where the above movement arrow line is visible when you click on Custom Animation of the picture at left of screen. This block of pictures streams across the screen repeatedly. Note the move-right Animation effect (dotted line with arrow on each end). Pre-Music - start it and stop it Click on the Music (speaker) icon the start the music. The description text Appears on that click also, as does the Stop icon. Click on the Stop icon to stop the music. The stop works by Action Setting Hyperlinking to the First Slide, which is itself (very cool).

The white box itself never appears during the presentation because the first animation on each slide is to remove it. ALL SUBSEQUENT SLIDES Most slides attempt to draw attention to the key item, letter, word, line, etc. by differentiating its color and/or size, and/or by animating it. When it is underlined too, it is totally for the benefit of the handout which cannot see these effects (except size). ALL SUBSEQUENT SLIDES Objects on most slides use consistent coloration effects. Code samples and boxes of diagrams usually use the gray Texture. Informational boxes use either a light blue (or blue-red) Texture, or a deep blue color either solid if small or shaded if larger.
