Question

wt are formating marks on why they are used​

Answer 1

Answer:

Special marks that are hidden by default that affect how text is displayed in a document. For example, with formatting marks enabled soft and hard returns are visible (shown right). In this example, the soft returns look like arrows pointing 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.
