Tsainta,
Are the lines in a placeholder, for instance bulleted text? That should be
easy, just apply an entrance effect using the custom animation taskpane.
Select the placeholder, click on add effect, entrance, fly in - crawl in,
next to direction choose from top. If they are seperate textboxes select
them all in the order of appearance, apply the entrance effect as described,
with the boxes still selected in the custom animation task pane next to
begin, choose on click.
