Each of the Transform tools
      (Rotate, Scale, Perspective, etc) can be set
      to act on a layer, selection, or path. Select the transform tool in the
      toolbox, then select
      
        
      
      layer,
      
        
      
      selection, or
      
        
      
      path for the
      Transform option in the tool's Tool Options
      dialog. This gives you a powerful set of
      methods for altering the shapes of paths without affecting other
      elements of the image.
    
By default a Transform tool, when it is set to affect paths, acts only on the active path which is shown highlighted in the Paths Dialog. You can make a transformation affect more than one path by selecting additional paths. Selecting multiple paths is done by using the mouse and Shift key, for adding a range of paths, or Ctrl key, for adding or removing the clicked path.
