UnderscriptBox

FilledSmallSquare UnderscriptBox[x, y] represents in input and output.

FilledSmallSquare Inside \( ... \) UnderscriptBox[x, y] can be input as x \+ y.

FilledSmallSquare In a notebook a UnderscriptBox can be created using ControlKeyLeftModified+RightModified. ControlKeyLeftModifiedRightModified moves out of the underscript position.

FilledSmallSquare In StandardForm and InputForm, UnderscriptBox[x, y] is interpreted on input as Underscript[x, y].

FilledSmallSquare UnderscriptBox[x, "_"] is interpreted as UnderBar[x] or . The input form x\&\%- can be used.

FilledSmallSquare The baseline of UnderscriptBox[x, y] is taken to be the baseline of x.

FilledSmallSquare UnderscriptBox[x, y] is usually output with y in a smaller font than x.

FilledSmallSquare With the option setting LimitsPositioning->True y is placed in an underscript position when the whole UnderscriptBox is displayed large, and in a subscript position when it is displayed smaller.

FilledSmallSquare In StandardForm, explicit UnderscriptBox objects are output literally. You can use DisplayForm to see the display form of such objects.

FilledSmallSquare See Section 2.9.10.
