Change the Sequence of Objects
Objects and groups of objects may be moved up and down the FilmStrip with the arrow (Layout Order) buttons.
Objects can only be moved within their current group within the FilmStrip. To move an object outside its group, Cut and Paste it. Alternatively, use Ungroup, move the object, and Group the remaining objects again.
You can move any object in the FilmStrip except the Root (first) entry.
To delete an object, select it in the FilmStrip and click Delete
