See where styles are applied in a document
Word can display color-coding for character styles, paragraph styles, linked paragraph styles, and manual formatting that is applied throughout your document. Color-coding enables you to quickly differentiate between text that is formatted by using styles, and text that is formatted manually. Color-coding also makes it easy to find and correct text to which styles were applied inconsistently. For example, text in the 12 point Cambria font and text formatted using the Normal style, which by default also uses the 12 point Cambria font, look identical. One important difference, however, is that text that is formatted by using a style can be quickly and globally changed to a different font. If you later decide to change the font, for example, each instance of text that you've formatted manually must be updated individually.
