ShowShortBoxForm
• ShowShortBoxForm is an option for cells that determines if box expressions, used to represent two-dimensional forms in a cell, are displayed in a more compact notation when the expression for that cell is viewed.
• With the setting ShowShortBoxForm 
True, the expression for a cell containing two-dimensional objects is represented in a compact notation, called ShortBoxForm. To view the expression for a cell, select the cell and click Format 
Show Expression.
• With the default setting ShowShortBoxForm False, cell expressions involving two-dimensional objects are not displayed in short box form. The short box form, though more compact, is less intuitive to read and interpret. Hence the conventional notation is preferred when viewing and editing cell expressions.
• For example, an input cell containing the expression 
would be displayed as: Cell[BoxData[\(a\^2 + b\^2\)], "Input"] with "ShortBoxForm" True; and as Cell[BoxData[RowBox[{SuperscriptBox["a", "2"],+",SuperscriptBox["b", "2"]}]], "Input"] with "ShortBoxForm" False.
