How to collapse cells in spyder notebook

[Matt Kriete]

Hi,

I am switching from using jupyter notebooks in a web browser to using spyder notebook. In the web browser interface I can collapse/fold all the cells under a given markdown heading level. When I open a notebook in spyder, I can see the cells are collapsed and reveal them by clicking on the button with the plus sign:

But once the cells are revealed I can't figure out how to re-collapse them. Is there a way to do this with spyder notebook?

Best,

Matt
