Answer:
Formatting marks.
Step-by-step explanation:
Microsoft Word can be defined as a software application designed and developed by Microsoft Inc. to allow users type and format text documents.
Simply stated, Microsoft Word is a word processing software application or program that users can use to type, format and save text-based documents.
Formatting marks are nonprinting characters that display within the text to designate formatting elements such as spaces, abs, and paragraph and line breaks.
Basically, the display of a formatting mark can be turned on or off depending on the choice of the user. When turned on, the formatting mark would be displayed on the Microsoft Word while it won't be displayed when turned off.
