Emacs: found that "dired-subtree" has a toggle behaviour!

In this short video I explain how I was able to discover two undocumented functions of dired-subtree, which define a toggle and a cyclical behaviour for expanding or contracting a subdirectory inside of Dired. I also discuss how to use the built-in methods of Emacs to discover such hidden features.

And this is a link to my configuration file, with all the settings I showed in the video as well as everything else, from previous screen casts: protesilaos.com/dotemacs.
