Resizing a window, narrower or wider

• Move the mouse pointer to the left hand edge of the Welcome Center window.  You will see that the mouse pointer changes shape to become a horizontal line with an arrow on each end. Press down the left hand mouse button and while keeping it pressed, move the mouse pointer left or right. When you release the mouse button the window will be narrower or wider, depending on which direction you move the mouse pointer.  Experiment with resizing the window to make it wider or narrower.
  
  Also experiment using the right edge of the window.
  
  TIP: Remember that this dragging action with the mouse button pressed is called ‘Drag and drop’.
