Reveal sidebar in Atom (editor)?

Question

I have a simple question. I've installed Atom and the package nuclide-commons, but when I open a folder, I don't see any sidebar with the list of files in Atom. I'm trying to find a way/shortcut to show it, but I failed. It's even not mentioned in the main menu...

Any hint? Thanks.

Answer 1

The shortcut is ctrl-\ or cmd-\ to open/close the Tree View

Answer 2

Ok, I had to enable the tree-view package in Atom settings. It was not enabled by default.
