MySQL Workbench
      To invoke the note editor, double-click a note object in the
      Model Note section on the MySQL
      Model page. This opens the note editor docked at the
      bottom of the application. Double-clicking the note tab undocks
      the editor. Double-click the title bar to redock it. Any number of
      notes may be open at the same time. Each additional note appears
      as a tab at the top of the note editor.
    
Use the editor to change the name of a note or its contents.
