Code-folding for Cython (.pyx) seems to be mostly not working in PyCharm Professional. The GUI shows some if/for loops as expandable with a + sign on the left-hand side. However, other loops and all function definitions are not expandable, either via the GUI or with keyboard shortcuts. PyCharm support pages indicate that code-folding is supported for Cython.
How do I enable full code-folding capabilities? Does it depend on the theme I am using (Dracula)? FWIW, I am on Ubuntu, using Gnome keyboard shortcuts.
