The Editor makes it easy not only to change the style of your text, but it also makes it equally easy to remove these styles.
To remove text styling applied to the document text, select the specific text and press the toolbar button. All text styling will be removed and the text is displayed with default paragraph formatting.
Note that this applies to style properties that are applied to the HTML source code by using the CSS stylesheet rules. This category includes most text styling methods as described in the Font Styling section (without paragraph format) as well as text alignment and indentation.
