WindowMargins
• WindowMargins is an option for notebooks that determines the size of margins around the notebook window.
• WindowMargins 
{{left, right
, {bottom, top
determines the distances from each edge of your screen to each edge of the window.
• The values of left, right, bottom, and top are given in points, where 72 points equal one inch.
• Negative values of left, right, bottom, and top represent edges that are off the screen.
• With WindowSize {Automatic, Automatic} all four margin distances must be given explicitly.
• With the default setting WindowMargins Automatic, new windows are placed on your screen in such a way as to make as many window title bars visible as possible.
• See also: WindowSize, WindowMovable.
