Folds

• Folds allow one to hide away parts of the code, so they won't interfere with the code flow.
• One can set up a fold using zf[movement].
• One can open a fold using zo.
• • zc closes a fold again.
  • zO opens all folds and sub-folds recursively.
• The :[Range]fold (or :[Range]fo) acts like zf.
• zE eliminates all folds in the window.
• zi toggles folding on and off.
