Opening and Closing Drawers and Folders

  The items on the Open-Close submenu of the main window's
  File menu let you open and close drawers and folders and
  open a drawer or folder in a new main window.

  If you are using a Paned style main window, this submenu is
  not available.  You can change the style of your main window
  by modifying your Window options.
