How to Edit Master Slides in PowerPoint 2007
Using master slides in PowerPoint presentations makes formatting your presentation easier. By designing master slides, you keep consistent backgrounds, colors, fonts, positioning and effects throughout all of the slides in your presentation. Once you design a slide master, PowerPoint carries the formatting and text through to all other slides in that group. If you want to make changes on individual slides, it is much quicker. You can also edit your master slide if you want to change the formatting on all the slides.
Open Microsoft PowerPoint.
Click "View" and select "Slide Master" from the "Presentation Views" group of the presentation you want to edit.
Choose the master slide you want to edit from your slides at the left.
Highlight any text where you want to change the size, color or style of your font. Click the "Home" tab and make your desired changes from the options in the ""Font" section.
Click the bullet options under "Paragraph" on the "Home" tab if you want to add any bullets. The button is the first one in the top row. Click the button to the right of the bullets to add a numbered list.
Click the "Slide Master" tab and choose "Background Styles" from the "Background" options if you want to edit the background. Select "Format Background." Choose your "Fill" options, any graphics you want to add to the background, stretch options and transparency of any graphics, then click "Close." You can preview your selections on the slide as you navigate through you background options.
Click on the "Slide Master" tab and click "Colors" under "Edit Theme" to change the color scheme for your master slide. Choose the new color scheme you want for your slides.
Click on any text boxes you want to resize. Use the sizing tools, the small squares on the border, to adjust the size to your preference.
Click the "Insert" tab and select "Text Box" from the "Text" options to add any new text boxes you want on your slides.
Click the "View" tab and select "Normal" once you are finished editing your master slide.
