PowerPoint 2002 includes a title master and a slide master for each design template. To add a slide master to an existing presentation:

• select the slides in the tabbed area.
• Format | Slide Design.
• In the Side Design Task pane, rest your mouse pointer over the design template you would like until a drop-down arrow appears.
• Click the drop-down list arrow and click apply to selected slides (or apply to all slides). When you apply a template to the selected slides, powerpoint automatically adds a slide and title master for the new template to your presentation.

To view the masters:

• View, Master | Slide Master.
• You can switch between the title and slide masters (and display the masters for a different template) by clicking the associated thumbnails on the Slide Tab.

• Display the Slide Master View toolbar: . View, Master | Slide Master.
• On the slide master view toolbar, click "Insert New Slide Master".

To retain a master after the slides have been deleted:

• Select it in the tabbed area.
• Display the Slide Master View toolbar: . View, Master | Slide Master.
• On the Slide Master View toolbar, click the "Preserve Master" button.
• You'll see the Pin icon appear next to the master slides.

To remove a preserved slide master:

• Click on the "Preserve Master" button again.

To disable the ability to save multiple slide masters (since earlier versions of PowerPoint don't support them):

• Tools | Options | Edit Tab.
• In the Disable New Features area, put a check next to the Multiple Masters box.
