How to ask Emacs for the current active folding mode?

Folding is active in my Emacs and looking into my `init.el` I can't figuring out why. :D So can I ask Emacs about the current active folding mode? Which is it? (e.g. hsminor, vdiff, origiami, ...)

Check the docstring of the `describe-mode` command.

If you can fold with a key press hit C-h k before hitting the key and it'll tell you which function it would call and where it's defined
