Automatically formats the file according to the options that you set under Tools - AutoCorrect - AutoCorrect Options.
When you apply automatic formats, the following rules apply:
A paragraph is formatted as a heading when the following conditions are met:
paragraph begins with a capital letter
paragraph does not end with a punctuation mark
empty paragraph above and below the paragraph
To create a bulleted list, type a hyphen (-), star (*), or plus sign (+), followed by a space or tab at the beginning of a paragraph.
To create a numbered list, type a number followed by a full stop (.), followed by a space or tab at the beginning of a paragraph.
Automatic numbering is only applied to paragraphs formatted with the Standard, Text body or Text body indent paragraph styles.
If you type three or more hyphens (---), underscores (___) or equal signs (===) on line and then press Enter, the paragraph is replaced by a horizontal line as wide as the page. The line is actually the lower border of the preceding paragraph. The following rules apply:
Three hyphens (-) yield a single line (0.05 pt thick, gap 0.75 mm).
Three underscore (_) yield a single line (1 pt thick, gap 0.75 mm).
Three equal signs (=) yield a double line (1.10 pt thick, gap 0.75 mm).
