For quick editing of your OpenOffice Impress presentation, you may choose to work only with the text. In that case, outline view is the answer. All the text of the slides is listed in the form of an outline. No graphics show in outline view.
Slides can be reordered by dragging the icon to the left of the slide title. When you let go of your mouse, the slide will be placed in the new location. Similarly, you may reorder the text of the bullet points on individual slides in the same manner.
