UnderscriptBox
UnderscriptBox[
x
,
y
] represents  in input and output.
Inside \( ... \)
UnderscriptBox[
x
,
y
] can be input as x \+
y.
In a notebook a UnderscriptBox can be created using   + .  moves out of the underscript position.
In StandardForm and InputForm, UnderscriptBox[
x
,
y
] is interpreted on input as Underscript[
x
,
y
].
UnderscriptBox[
x
,
"_"] is interpreted as UnderBar[
x
] or  . The input form x\
&\%- can be used.
The baseline of UnderscriptBox[
x
,
y
] is taken to be the baseline of x.
UnderscriptBox[
x
,
y
] is usually output with y in a smaller font than x.
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.
In StandardForm, explicit UnderscriptBox objects are output literally. You can use DisplayForm to see the display form of such objects.
See The Mathematica Book on the web:Section 2.8.10.
