Navigating around long, complicated documents can be slow and a little tedious. I offered one possible workaround in this post, but a new Google Docs feature helps even more.
The new Outline Tool displays in a panel to the left of the page, where it lists headers for each section of your document. Using these links you can quickly hop from section to section within the document.
To open the tool in your document, click Tools > Document outline.
If you haven’t manually applied headers, the Outline Tool tries to do it for you, detecting the logical divisions within the document. You can then edit or remove these headers as necessary.
The tool is available on Android, too.
