Thumb indexes are small round sections of a book that are cut out to make it easy for you to navigate the different sections. In Microsoft Office Word, you can create a digital thumb index for longer documents to make navigation easy.

Let’s say that you would like one tab for each division in your Word document (such as chapters or alphabetized sections). You want a tab for the first page of the section, and it will appear on the right-hand side. Finally, let’s imagine that you would like these tabs to be black or some other dark color, with white text.

You can create these tabs as a tall, thin (single-column, multi-row) table that is attached to the Header. This table will be identical in all the sections, but in each particular section, there will be a different highlighted row with text.

Instructions in this article apply to Word 2019, Word 2016, Word 2013, Word 2010, and Word for Office 365.
