The best approach to formatting in OpenOffice.org presentations is to let all the formatting flow from the template.
If you do manual formatting on some words in the presentation, then that will stick when you switch or modify the template. Then you'll be stuck with a few red headings, or other formatting that doesn't look good in the new or modified template.
Here's what you do to remove all that manual formatting and let the template formatting flow through to every part of every slide.
- Click the Outline tab at the top of the work area.
- Click in the text area of the Outline tab and Select All.
- Choose Format > Default Formatting.
And there you are. All the manual formatting is gone, and your presentation adapts to whatever template you're on.
