Every slide is based on a slide master. The text, pictures, tables, fields or other objects that you place on the slide master are visible as a background on all slides that are based on that slide master.

Masters exist for slides, notes, and handouts.

• To edit a slide master, choose View - Master - Slide Master. Click the Close Master View icon on the Master View toolbar, or chooseView - Normal, to leave the slide master.
• To edit a notes master, choose View - Master - Notes Master. Click the Close Master View icon on the Master View toolbar, or chooseView - Normal, to leave the notes master.
• To edit a handout master, click the Handout tab above the slide. Click the Normal tab to leave the handout master.

Adding predefined header or footer objects

Every type of master has some predefined areas to hold the date, footer, and slide numbers.

When you switch to the master view, you can move that areas to any position on the master. You can enter additional text and resize the areas. You can select the contents of the areas and apply text formats. For example, you can change the ‍font size or color.

A predefined Header Area is available only for notes and handouts. If you want a header on all slides, you can move the Footer Area on the slide master to the top.

Objects that you insert on a slide master are visible on all slides that are based on that slide master.

1. Choose View - Header and Footer.
   You see a dialog with two tab pages: Slide and Notes and Handouts where you can enter contents to the predefined areas.
   By default, the Date and Time checkbox is enabled, but the format is set to Fixed and the text input box is empty, so no date and time is visible on the slides.
   By default, the Footer checkbox is enabled, but the text input box is empty, so no footer is visible on the slides.
   By default, the Slide number checkbox is cleared, so no slide numbers are visible.
2. Enter or select the contents that should be visible on all slides.
3. If you want to change the position and formatting of the master objects, chooseView - Master - Slide Master.
