Every slide is based on a master slide. The text, pictures, tables, fields or other objects that you place on the master slide are visible as a background on all slides that are based on that master slide.
Masters exist for slides, notes, and handouts.
To edit a master slide, choose View - Master Slide. Click the Close Master View icon on the Master View toolbar, or choose View - Normal, to leave the master slide.
To edit a master notes, choose View - Master Notes. Click the Close Master View icon on the Master View toolbar, or choose View - Normal, to leave the master notes.
To edit a master handout, click the Handout tab above the slide. Click the Normal tab to leave the master handout.
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 those areas to any position on the master. Also, you can enter additional text into them, resize them, and select their contents to apply text formatting. 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 master slide to the top.
Objects that you insert on a master slide are visible on all slides that are based on that master slide.
Choose Insert - Header and Footer.
You see a dialog with two tab pages: Slides 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.
