What feature allows users to quickly navigate through pages of a document's images?

The thumbnail feature provides users with a visual overview of a document's images, allowing for quick navigation through its pages. By displaying smaller versions of each page, users can easily scan for specific images or sections they want to view in detail. This functionality is particularly useful in large documents, as it simplifies the process of locating content without having to scroll through each page individually.

This contrasts with the other options, which do not focus on navigation. The highlight tool, for example, is designed for marking text or images for emphasis but does not aid in navigating the document. The text editing tool allows for modifications to the document's text, and while it is valuable for document management, it does not assist with page navigation. Similarly, the production mode selector pertains to how the document is prepared or displayed, rather than facilitating quick navigation through image pages.
