UnderoverscriptBox[x,y,z]
is the low‐level box representation for 
in notebook expressions.
Details and Options
- UnderoverscriptBox is the low-level representation of Underoverscript. Except for low-level notebook expression manipulation, UnderoverscriptBox should not need to be used directly.
- Inside \(…\) UnderoverscriptBox[x,y,z] can be input as x\+y\%z.
- To create an UnderoverscriptBox in a notebook, use either
to create a normal underscript or 
to create a normal overscript. After typing the first script, use 
to create the opposite script position. 
moves out of the underscript or overscript position. - The following options can be given:
-
BaseStyle {} the style to use DiacriticalPositioning Automatic where to draw diacritical marks LimitsPositioning Automatic whether to position scripts in a way conventional for limits MultilineFunction Automatic how to handle scripts so long that linebreaking may be necessary - In StandardForm, UnderoverscriptBox[x,y,z] is interpreted on input as Underoverscript[x,y,z].
Examples
Basic Examples (3)
Display a letter with an underscript and an overscript:
UnderoverscriptBox["x", "0", "1"]//DisplayFormAn UnderoverscriptBox form is typically interpreted as an Underoverscript expression:
ToExpression[UnderoverscriptBox["x", "0", "1"], StandardForm]%//FullFormThe standard formatting for Underoverscript uses UnderoverscriptBox:
ToBoxes[Underoverscript[x, 0, 1], StandardForm]//FullFormThe formatted result looks like this:
