Too Long; Didn't Read
Folding has been rolled out and is now implemented since Visual Studio Code version 0.10.11. Folding folds the innermost uncollapsed region, while Unfold unfolds the collapsed region at the cursor. This is a personal documentation of this process for that point in time when I need this useful information again. WARNING: Watch out for the ZERO key listed, it is not an "O" key. It is meant to be pressed while the other key is held down.
