Hi Keith

I think you want the `linkClicked` message. Navigation via links is under script control so possibly what you want is:

on linkClicked pAction
   if pAction[“type”] is “goto” then
       set the currentDestination of me to pAction
   end if
end linkClicked

Following the PDF guide https://livecode.com/resources/guide/ I’ve been able to load various PDF documents into the viewer widget and view, paginate, scroll, etc. I can select text, as per the example code in the guide and this ability to select toggles with the autoHighlight property on the widget - as expected. However, I’m struggling to get much else.

There are no hovers or navigation on obvious links or bookmarks. Furthermore, other than documentPages and documentMetadata, all of the arrays that should handle these navigation elements are empty - documentBookmarks, documentNamedDestination, linkStyles.
