+   Panel objects have the following methods:
 
 
-.. method:: Panel.above()
+.. method:: panel.above()
 
    Returns the panel above the current panel.
 
 
-.. method:: Panel.below()
+.. method:: panel.below()
 
    Returns the panel below the current panel.
 
 
-.. method:: Panel.bottom()
+.. method:: panel.bottom()
 
    Push the panel to the bottom of the stack.
 
 
-.. method:: Panel.hidden()
+.. method:: panel.hidden()
 
    Returns ``True`` if the panel is hidden (not visible), ``False`` otherwise.
 
 
-.. method:: Panel.hide()
+.. method:: panel.hide()
 
    Hide the panel. This does not delete the object, it just makes the window on
    screen invisible.
 
 
-.. method:: Panel.move(y, x)
+.. method:: panel.move(y, x)
 
    Move the panel to the screen coordinates ``(y, x)``.
 
 
-.. method:: Panel.replace(win)
+.. method:: panel.replace(win)
 
    Change the window associated with the panel to the window *win*.
 
 
-.. method:: Panel.set_userptr(obj)
+.. method:: panel.set_userptr(obj)
 
    Set the panel's user pointer to *obj*. This is used to associate an arbitrary
    piece of data with the panel, and can be any Python object.
 
 
-.. method:: Panel.show()
+.. method:: panel.show()
 
    Display the panel (which might have been hidden), placing it on top of
    the panel stack.
 
 
-.. method:: Panel.top()
+.. method:: panel.top()
 
    Push panel to the top of the stack.
 
 
-.. method:: Panel.userptr()
+.. method:: panel.userptr()
 
    Returns the user pointer for the panel.  This might be any Python object.
 
 
-.. method:: Panel.window()
+.. method:: panel.window()
 
    Returns the window object associated with the panel.
