There are two types of word directories, which can be added manually or automatically. Is it troublesome to add the above directories manually? If the content is fixed, a manual catalog is barely acceptable. If it were to revise the manuscript, wouldn't all the workers there be killed? Word also has the function of automatically adding a table of contents and automatically updating the table of contents and pages, which is very powerful and easy to operate. However, automatic catalogs and updates require good document editing habits and are done in a clean and consistent style. Microsoft Office Word is a word processing application from Microsoft. It was originally written by Richard Brodie in 1983 for IBM computers running DOS. Subsequent versions ran on Apple Macintosh (1984), SCO UNIX, and Microsoft Windows (1989), becoming part of Microsoft Office.
