Styles, Automatic Table of Contents and Track Changes in Word

When preparing a long report, thesis or contract, two problems come up again and again: headings look inconsistent, and typing a table of contents by hand takes a lot of time. On top of that, when a document passes through several people, it becomes hard to see who changed what. In this article, based on Microsoft's official guides, we explain three useful Word tools: styles, the automatic table of contents and Track Changes.

What is a style in Word and why do you need it?

Built-in styles are combinations of formatting characteristics that you apply to text to quickly change its appearance (font, size, colour, spacing and so on). Instead of formatting each heading separately, you pick a style — and the same look is kept throughout the document.

The main advantages of styles:

  • formatting stays consistent throughout the document;
  • when you change a style, all text in that style updates at once;
  • heading styles are the easiest way to create a table of contents.

How do you create an automatic table of contents?

A table of contents in Word is based on the headings in your document. The steps are:

  1. Select each heading and apply the Heading 1, Heading 2 or Heading 3 style from Home > Styles.
  2. Place the cursor where the table of contents should go.
  3. Choose a suitable layout from References > Table of Contents.

After adding new headings or when pages change, right-click the table of contents and choose Update Field — the table of contents will be refreshed.

Use Heading 1 for main sections, Heading 2 for subsections and Heading 3 for smaller headings. That way the table of contents is neatly arranged by level.

Track Changes: how do you track edits?

When you send a document to a colleague or teacher, it is important to see their edits. To do this, turn on Review > Tracking > Track Changes. After that:

  • deleted text is shown with a strikethrough;
  • added text is shown underlined.

By right-clicking each change you can accept or reject it. This way you decide what stays in the final version.

Who needs these tools most?

  • Office staff — reports, internal documents, letters;
  • students — coursework, theses, essays;
  • lawyers and accountants — agreeing contracts and reports with several people.

Styles and a table of contents make a document look professional, while Track Changes saves time in teamwork.

Summary

  • A style is a set of formatting that quickly changes the look of text.
  • Styles help keep the same formatting throughout a document.
  • The table of contents is based on Heading 1, 2, 3 headings: References > Table of Contents.
  • To update the table of contents: right-click > Update Field.
  • In Track Changes, deletions are struck through and additions are underlined.
