What step allows you to apply formatting to more than one location in a document using the Format Painter button?

To apply formatting to more than one location in a document using the Format Painter button, double-click the Format Painter icon instead of single-clicking it. This action locks the Format Painter mode, allowing you to click on multiple text areas or objects to apply the same formatting repeatedly. Once you're done, you can exit this mode by pressing the "Esc" key or clicking the Format Painter icon again.
