  3. Choose Animation > Animate Text > Opacity.
  4. Set Opacity to 0%.
  5. Expand the Range Selector 1 and click the stopwatch icon for Start.
  6. In the Composition panel, drag the start selector to the left edge of the text (the value will be at 0).
  7. Move the current-time indicator to 5 seconds and drag the start selector in the Composition panel to the right edge of the text (the value will be 5).
  8. Preview the composition.
    Note: By default, the Smoothness property is set to 100%. To create a typewriter appearance, expand the Advanced property and set Smoothness to 0%.
