To indent the first line of a paragraph, you should use the B Tab key.

Explanation: Indenting is a typographical feature that creates an empty space at the beginning of a line, shifting it to the right. In most word processing software and text editors, pressing the Tab key on your keyboard will create a default indentation. This is commonly used when starting a new paragraph to visually distinguish it from the previous one and make the text more readable.
