How to Remove Formatting From Text in InDesign
Adobe InDesign is a design and publishing application that you can use to create print and digital publications. When you create a document using InDesign, the font, text size and other formatting characteristics are determined by your default style settings. You can change these formatting defaults by applying changes at the character-by-character or paragraph-by-paragraph level. You can remove any formatting changes you've made to your InDesign document using the program's Paragraph Styles menu.
Run the Adobe InDesign application.
Click "Type" in the application menu and choose "Paragraph Styles." Doing so will open the Paragraph Styles menu on the right side of the InDesign program window.
Highlight the text from which you wish to remove formatting.
Hold down your keyboard's Ctrl key if you wish to only clear formatting that was created on the character level. If you are using a Mac hold down the Command key.Hold down the Shift and Ctrl keys if you wish to only remove formatting that was applied on a paragraph-by-paragraph basis. If you're using a Mac, instead hold down the Shift and Command keys.
Click on "Clear Overrides" in the Paragraph Styles panel. Doing so will remove formatting from the selection and will revert the style to your document's default style.
