If you have your Type tool in a text frame in InDesign and start editing a Paragraph or Character Style, you’ll end up assigning any style you click on to the selected text. If you don’t want to apply that style to the selected text or paragraph, hold down Shift+Option+Command (Mac) or Shift+Alt+Ctrl (PC) and double-click on the style name you wish to change. Alternately, Control- or right-click on the style name in the panel and choose Edit “Style Name.”
