Using docbook and Apache FOP I can create PDFs that contain cross-references. For example, the Table of Contents of a book looks like this:

 Chapter 1 Introduction........................12

Using the ancient xpdf I can click on the page number 12 and be taken to page 12. Whenever the pointer is on a cross-reference (also for references to figures, tables, sections, etc.) it turns from an arrow into a left-pointing hand to indicate "click me to follow the reference". evince can do the same.

For some reason, okular appears unable to do this. I tried left-middle-right clicks, with and without CTRL, ALT, SHIFT keys. Is this just a configuration snag? Or is okular in fact unable to follow cross-references?

I'm using "Okular 0.20.2 Using KDE Development Platform 4.14.2" on FreeBSD 11.

    The short answer is yes, it does, but I don't have any idea why it wouldn't be working for you. There is a "draw border around links" setting (under "Accessibility") that would let you diagnose whether it was the interaction or the detection that was broken. – Michael Homer Jan 4 '15 at 19:12
  • @MichaelHomer I've turned it on and it does indeed draw the borders around the links. What do you do to follow a link? Just left-click? – Jens Jan 4 '15 at 20:22
  • Yes. Right-click gives a one-item menu with a "Follow This Link" entry. – Michael Homer Jan 4 '15 at 20:24
  • @MichaelHomer Hmm. Left-click does nothing. Middle-click enables continuous zooming. Right click brings up a 4-entry menu with the page number as the title and "Add Bookmark", "Fit Width", "Next Bookmark", "Previous Bookmark". – Jens Jan 4 '15 at 20:28
  • @MichaelHomer Solved it: You have to be in "Browse" mode; in "Zoom" mode or "Selection" mode following links is disabled/replaced by a different function. – Jens Jan 4 '15 at 20:41

It wasn't a configuration snag, but a user interface snag: following links works while using the "Browse Tool" (Icon: mouse), but not while using the "Zoom Tool" (Icon: Looking glass over paper sheet) or the "Selection Tool" (Icon: pencil in corner of frame).

  • Wow... same here. Seems like a bit of a user interface failure. – Manfred Moser Oct 4 '16 at 16:03
