Q. In Microsoft PowerPoint, is there a way to change the font on all of the slides at once?

Open up a PowerPoint presentation. Select the View tab and click Slide Master. To make all the text in your presentation the same font, in the Edit Theme box, click on Fonts. You can select a font that will be applied to the text on all of your slides. To make the heading and body text of your slides different fonts, select Fonts from the Edit Theme box, but instead of choosing one font, select Create New Theme Fonts. This will open up a new dialog box that will allow you to select different fonts for your heading and body text.
