Hi Maura,
If your intent is to simulate the formatting commonly found in a book's
table of contents or index (in order to visually connect columns of
text on the far left and far right of a slide), I would suggest using a
table. From there, you could use alternating fill colors by row, or
different horizontal line styles within the table.
Hope this helps,
Tony
