In many types of documents, you may want to indent only the first line of each paragraph. This helps to visually separate paragraphs from one another.
A quick and common way to indent is to use the Tab key. This will create a first line indent of a half-inch.
If you want to indent all lines in a paragraph, you can use the Increase indent and Decrease indent shortcut buttons.
You can also click Format from the menu toolbar and select Paragraph styles to locate the Increase indent and Decrease indent commands.
