LimitsPositioning
• LimitsPositioning is an option for cells that determines whether or not to change the positioning of underscripts and overscripts in the way conventional for limits.
• UnderoverscriptBox[x, y, z, LimitsPositioning 
False] is always displayed with explicit underscripts and overscripts, as 
.
• UnderoverscriptBox[x, y, z, LimitsPositioning True] is displayed as 
when large, and 
when small.
• The 
form is used when the box appears in a subscript or other script, or inline in a piece of text.
• With the default setting LimitsPositioning Automatic, the display of UnderoverscriptBox[x, y, z] depends on x. If x is \[Sum], \[Product] or another form conventionally displayed with limits, then LimitsPositioning True is effectively used. Otherwise, LimitsPositioning False is used.
• LimitsPositioningTokens is a Cell option that can be set to a list of forms for which LimitsPositioning True should be used.
• See also: LimitsPositioningTokens, ScriptSizeMultipliers.
DiacriticalPositioning
• DiacriticalPositioning is an option for cells that determines how close diacritical characters are drawn to the base character.
• With the setting DiacriticalPositioning True, characters that occur in an underscript position are drawn relatively close to the base character .
• With the setting DiacriticalPositioning False, characters that occur in an underscript or overscript position are drawn at a greater separation from the base character.
• With the default setting DiacriticalPositioning Automatic, a selected set of characters, which are normally used as diacritical marks, are by default drawn close to the base character when used in an underscript. All other characters are drawn at a greater separation from the base character.
MultilineFunction
• MultilineFunction is an option for cells that determines if an underscript is split to the next line if it is too long to fit on one line.
• With the default setting MultilineFunction Automatic, a underscript may be reformatted to extend across two or more lines. The point at which the line break is applied is indicated by a 
symbol.
• With the setting MultilineFunction None, no reformatting is done.
