2 In the Parameter row, click the Add pop-up menu, then choose Format > Opacity.
The Opacity parameter is added in the Behaviors tab above the Add and Remove pop-up
menus.
3 In the Inspector, set Opacity to 0 and play the project (press Space bar).
Because the Sequencing parameter is set to From by default, the opacity sequences from
the value set in the behavior (0%) to original value of the text (100%).
4 Click the Sequencing pop-up menu and select To.
Now when you play the project from the beginning, the opacity fades to the value set in
the behavior (0%) from the original value of the text (100%).
5 Click the Add pop-up menu, choose Format > Scale, then click again and choose Glow
> Scale.
The Scale and Glow Scale parameters are added to the Behaviors tab.
