Text styles can be applied to text within your designs for efficiency and consistency.
A text style is a set of one or more attributes which can be applied to text in bulk. Later, if you chose to modify a text style, any text which uses that style will update to conform to the changes you've made.
Every new document comes with a default set of text styles but the Text Styles panel provides you with the ability to create and manage a document's text styles as well as remove them.
Text styles can be applied to text using the Text Styles, Paragraph or Character panels, the context toolbar or a custom keyboard shortcut.
Furthermore, if you have established a strict order for your text styles, using Next Style, you can apply an entire set of text styles to a story (or portion of a story) in one go.
If local formatting has been applied, this can be quickly removed using the Text Styles panel, leaving the currently applied text styles in place.
