In this task, you will check out content from a space
  so that others cannot modify the file with which you are
  working.
    - 
        In the Drafts space, click 
 and select
        Check Out for the document
        system-overview.html.
         You are given the choice of checking out the working
        copy to the same space as the original or to any other space. Some
        people like to work with one space that contains all their current
        work-in-progress, so may have created a specific folder in their home
        space for working copies. You are going to keep the working copy in
        the current space.
        
 - Click Check Out.
 - Click the link system-overview (Working Copy).html and save the file to your computer.
 - 
        Click OK to return to the space, which now
        contains two items. One is appended with (Working
        Copy).
