 The PDF viewer allows navigating from one part of the PDF document to another using document link annotations. When a document link annotation is tapped, the PDF viewer scrolls to the destination page or location defined by that annotation. This type of annotation is most commonly used to make a PDF's table of contents interactive — each entry links directly to the corresponding page in the document.

 N> Document link annotations differ from hyperlink annotations. Document links navigate **within** the same PDF document, while hyperlinks open an external URL in the device browser. See [Hyperlink Navigation](https://help.syncfusion.com/document-processing/pdf/pdf-viewer/maui/hyperlink-navigation) for details on handling external links.

 # Form Filling in .NET MAUI PDF Viewer (SfPdfViewer)
 
-The .NET MAUI PDF Viewer [SfPdfViewer](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html) enables users to view and fill AcroForm-based PDF forms across mobile and desktop apps. It supports interactive form filling through the built-in UI, and developers can access and modify form data programmatically using the `FormFields` API.
