Help & Manual automatically generates a number of named destinations in your PDF files,which can be used as link targets in the same way as anchors. You don't need to use named destinations for normal topic links topics inside a project, those work in PDFs without any action on your part. However, named destinations are useful if you want to link to a specific location in a PDF from a HTML page, another PDF file or an application.
See Named destinations in PDF for full details on the available named destinations you can use.
1.If the PDF you are linking to is created with Help & Manual it must be generated using the "interactive PDF" option in your PDF settings.
2.Create an Internet link to the PDF file you want to open, using the normal URL syntax for Internet links.
3.Add #nameddest=destination directly after the PDF filename, where "destination" is the the named destination you want to jump to. This is case-sensitive, upper and lower case must match the actual destination exactly.
You can also use the abbreviated syntax #destination, which is supported by all current versions of Adobe Reader.
