The Show and Hide Formatting Symbols button on the ribbon toggles on and off the ability to see non-printing characters.
Step-by-step explanation:
The Show and Hide Formatting Symbols button on the ribbon toggles on and off the ability to see non-printing characters.
The Show and Hide Formatting Symbols button in word processing software allows users to see non-printing characters for editing and reviewing document formatting.
The button on the ribbon that toggles on and off the ability to see non-printing characters in a document is known as the Show and Hide Formatting Symbols button.
This feature is particularly useful when you want to review or edit the formatting of a document. It displays symbols that represent spaces, tabs, paragraph marks, and other formatting elements that are usually invisible, making it easier to understand the document's structure.
In Microsoft Word, for example, this button is represented by the ¶ (pilcrow) symbol.
