25.6 Filling Text
Filling text means breaking it up into lines that fit a specified width. Emacs does filling in two ways. In Auto Fill mode, inserting text with self-inserting characters also automatically fills it. There are also explicit fill commands that you can use when editing text.
| • Auto Fill | Auto Fill mode breaks long lines automatically. | |
| • Fill Commands | Commands to refill paragraphs and center lines. | |
| • Fill Prefix | Filling paragraphs that are indented or in a comment, etc. | |
| • Adaptive Fill | How Emacs can determine the fill prefix automatically. |
