It was pointed out in Where I can find the CD version of Stan Wagon - "Mathematica in action" 3rd ed. book? that the code for Wagon's book is available at http://extras.springer.com/2010/978-0-387-75366-9

I have downloaded all the notebooks from that site, but when I click on any of them, it will open up in Mathematica, but all I see is the section headings. For example when I open the notebook for chapter 1 I get the following

enter image description here

I am using Mathematica 11.1.1.0 on mac os x. Is there some trick that I need to employ to actually see the code?

    $\begingroup$ To you see those brackets with the arrow pointing down at the right of the screen? Try to double click on them; they shoul expand... $\endgroup$ – Henrik Schumacher May 1 '18 at 12:46
  • $\begingroup$ @Henrik, thanks this does indeed work, but with one caveat -- namely you must right double click, rather than the usual left double click. $\endgroup$ – Richard Gostanian May 1 '18 at 14:42
  • $\begingroup$ Oh? For me it's a left double click... $\endgroup$ – Henrik Schumacher May 1 '18 at 14:44
  • $\begingroup$ @Henrik, maybe the OS makes a difference. I'm on Mac OS X, what are you running on? $\endgroup$ – Richard Gostanian May 1 '18 at 16:15
  • $\begingroup$ Also macOS. But maybe I made some nonstandard system setting years ago. Doesn't matter, though. $\endgroup$ – Henrik Schumacher May 1 '18 at 16:17
