Special marks that are hidden by default that affect how text is displayed in a document. For example, in the picture to the to the right, with formatting marks enabled soft and hard returns are visible. In this example, the soft returns look like arrows pointing to the left and the hard returns is a paragraph mark, which looks like a backwards 'P'. Formatting marks are often used to troubleshoot a document's layout, appearance, and any printing problems and can be enabled or disabled depending on your preference.
