OpenersNotesSection(Spacer1)Details and Options

(RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox]) is the low-level representation of (RefLink[Underoverscript, paclet:ref/Underoverscript]). Except for low-level notebook expression manipulation, (RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox]) should not need to be used directly.

Inside \(…\) (RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox])[x,y,z] can be input as x\+y\%z.

To create an (RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox]) in a notebook, use either (Key1[ctrl, $]) to create a normal underscript or (Key1[ctrl, &]) to create a normal overscript. After typing the first script, use (Key1[ctrl, %]) to create the opposite script position. (Key1[ctrl, space]) moves out of the underscript or overscript position.

In (RefLink[StandardForm, paclet:ref/StandardForm]), (RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox])[x,y,z] is interpreted on input as (RefLink[Underoverscript, paclet:ref/Underoverscript])[x,y,z].

Display a letter with an underscript and an overscript:

UnderoverscriptBox["x","0","1"]//DisplayForm

An (RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox]) form is typically interpreted as an (RefLink[Underoverscript, paclet:ref/Underoverscript]) expression:

ToExpression[UnderoverscriptBox["x","0","1"],StandardForm]

%//FullForm

The standard formatting for (RefLink[Underoverscript, paclet:ref/Underoverscript]) uses (RefLink[UnderoverscriptBox, paclet:ref/UnderoverscriptBox]):

ToBoxes[Underoverscript[x,0,1],StandardForm]//FullForm

The formatted result looks like this:

Underoverscript[x,0,1]
