Intro: When viewing a PDF-file with a bookmark tree, I can unfold(open) nodes in the bookmark tree and make the view window jump to the corresponding destination.
If the bookmark tree is open (unfolded) I can observe a selection mark moving downwards in the bookmark tree as I move down in the content.
Question: Is it possible to make the folded bookmark (outline) tree open dynamically as I move down in the content? I would like to see the bookmark tree unfold automatically and move the highlight to the bookmark (outline) node for the bookmark position nearest to (above) the view point in the content window.
Additonal remark to my question: It would also be satisfactory if I could unfold on request, i.e. clicking somewhere in the content, invoke the context menu (right-click) and then choose something like: Unfold path in bookmark tree.
You can't make the bookmarks navigation pane dynamic.
There is an "expand current bookmark" icon on the pane header (bookmark symbol with a right-pointing arrow). This will expand whichever bookmark relates to the current cursor position within the document, but it cannot be made to react automatically, nor is it accessible to scripting.
thank you for quick and precise answer.
