Add text placeholders to slide masters in Keynote ’08

You may have noticed that there’s no intuitive way to add your own text placeholder to a master slide in Keynote ’08. In other words, if you want to make a set of slides that has more than just a title and body you can either (1) add a text box on every page or (2) try to add a text placeholder to Keynote. The second option isn’t so intuitive, but here’s how to do it:

1. Select View » Show Master Slides.
2. Select the master slide you want to edit. Make a text box in a master slide and keep it selected.
3. In the Inspector, go to the Slide Inspector (second from left), and select the Appearance tab.
4. Check the checkbox next to Define as Text Placeholder, and create a tag.
