https://macmost.com/e-1718 There are two main methods for replacing a font in Pages. Typically, you would want to update some text and then apply that font change to the rest of the text that uses that same style. You can do that with a simple press of a button. But if you want to quickly replace a font that is used in multiple styles, you can use a special Replace Fonts function. This not only changes the text, but also updates all styles.
