For longer documents a table of content is a great way to help your readers find exactly what they are looking for. It puts a list of links at the beginning of your document that point to different sections of that document. Clicking the right link instantly transports you to the exact place in the document you want to be. Once you’ve created your table of contents, you can easily update its links as you edit each section of your document.
Previously, we’ve seen how to do this in Word and it works much the same way in Google Docs.
To make a table of contents, you need to mark each section of your document with a heading. To do this, highlight the appropriate text, and then select a heading size from the style menu in the toolbar.
After you’ve marked each section with a heading, you can then add a table of contents from the Insert menu. ( Insert » Table of contents )
