is it possible to go to the folders via the sidebar?

[Globe Trotter]

I am new to mutt, and have sidebar enabled and a list of my folders to the left. I can go down the list of the folders, using my keyboard. But I can not figure out how to get into them directly (after highlighting them). Is there a way? Right now, I am reduced to typing c -> =foldername and then going to the list. Kind of makes the sidebar not at all useful for me so I am thinking that there must be a better value for the sidebar folders.

Btw, after using mutt for two 2 days, it has been a lot of fun. (The initial frustration has worn out.) Thanks to all the developers and also the members of the users list for their very helpful answers and directions!
