Add and edit master slides

The slide layouts used in each Keynote theme are based on master slides. When you want to add a slide to your presentation that has particular elements—such as a title and subtitle, a bulleted list, or an image—you select the slide layout that most resembles the layout you want, then you replace the placeholder elements and make other changes as necessary. Only the slide in your presentation is changed; the master slide remains in its original state.

If you add new images, text, and other objects to a master, these objects become part of the slide background and aren’t editable in your presentation. If you want text, shapes, or images to be editable in your presentation, you must add them as placeholders to the master slide.

You can make changes to a master slide like you can to a regular slide—including modifying the appearance of text, changing the slide background, and changing the size of the images. When you do, the changes appear on every slide in the presentation that’s based on that master.

Edit master slide mode

Add a master slide

  1. Click View View button in the toolbar, then choose Edit Master Slides.

  2. Do any of the following:

    • Click Add slide button in the toolbar, then select a master slide.

    • In the slide navigator, select a slide with a layout similar to the layout you want, and press Return.

  3. Double-click the name of the master slide in the slide navigator and type a new name.

  4. Modify the slide however you like by adding text, images, shapes, placeholders, or other objects.

    If you want objects on a master slide to layer with objects you add to slides based on that master, select “Allow objects on slide to layer with master” in the sidebar. To learn more about layers, see Layer, group, and lock objects. (If you don’t see a sidebar, or the sidebar doesn’t have the “Allow objects on slide to layer with master” checkbox, click Format button in the toolbar.)

  5. Click Done at the bottom of the slide canvas, or click View View button in the toolbar, then choose Exit Master Slides when you’re done editing.

Add text, image, and shape placeholders

  1. Click View View button in the toolbar, then choose Edit Master Slides.

  2. Select the master slide you want to edit.

  3. Add a text box, an image, a video, or a shape to the slide, change its appearance however you want, then place it where you want it to appear on the master slide.

  4. Select the text box, image, video, or shape, then near the bottom of the sidebar, select Define as Text Placeholder (for a text box or a shape) or Define as Media Placeholder (for an image or a video).

    If you don’t see a sidebar, or the sidebar doesn’t have the Define as Placeholder checkbox, click Format button in the toolbar.

  5. Click Done at the bottom of the slide canvas, or click View View button in the toolbar, then choose Exit Master Slides when you’re done editing.

Add an object placeholder for a table and chart

To create a placeholder on a master slide for a table and chart, add an object placeholder. On any slide based on the master, you can add a table or chart and the table or chart assumes the size and position of the object placeholder.

  1. Click View View button in the toolbar, then choose Edit Master Slides.

  2. Select the master slide you want to edit.

  3. Select the Object Placeholder checkbox in the sidebar.

    If you don’t see a sidebar, or the sidebar doesn’t have the Object Placeholder checkbox, click Format button in the toolbar.

An object placeholder is added to your slide; you can resize it and position it where you want. Only one object placeholder can be added to a master slide.
