What happens if both workbook help and worksheet help are defined?

When both workbook help and worksheet help are defined, help will display as separate tabs in the help pane. This means that users who are accessing the help documentation can easily navigate to either the general workbook information or the specific information related to the worksheet. This dual availability enhances usability by providing context-specific guidance while also offering broader assistance relevant to the entire workbook. Users benefit from a more organized interface, allowing them to find the information they need without confusion, thus improving their overall experience with the workbook.
