In which tab can you find the Title button necessary for updating the header?

The Title button, which is used for updating the header in a document, can be found in the Design Ribbon Tab. This tab contains various tools and options for formatting and designing your document's layout, including headers, footers, and other stylistic features. By utilizing the Design Ribbon Tab, users have access to specific functionalities that allow for intricate adjustments to the document’s presentation, such as modifying the header for title styles or other design elements.

In contrast, other tabs such as the Home, Insert, and View Ribbon Tabs focus on different aspects of document creation and editing, such as text formatting, inserting objects, and altering document views, which do not include options for directly updating the header title. This distinction helps in efficiently navigating the tools available in the software to achieve desired document formatting outcomes.
