Craig,
If you wanted to get things exactly as you typed them you might type them, expose the underlying expression and them copy that box structure into your NotebookWrite. For example:
NotebookWrite[EvaluationNotebook[], RowBox[{"Integrate", "[", RowBox[{RowBox[{"x", " ", RowBox[{"y", "^", "2"}]}], ",", RowBox[{"{", RowBox[{"y", ",", "1", ",", "2"}], "}"}]}], "]"}]]
This is a bit of work if you want to do much of it.
But how are you using this that it is so important that it be exactly as typed?

Hello Mathgroup,
I'd like to have NotebookWrite[] create an input cell *exactly* as I have typed that input cell. I'm trying to create set of tutorials with exercises and worked solutions.
Here are two *almost working* method, however they don't reproduce the code as it is writtenwhich is what I'm trying to do. I'm stuck.
(*Method 1*) SetAttributes[expressionCell, HoldAll];
expressionCell[expr_] := NotebookWrite[EvaluationNotebook[], Cell[Block[{BoxForm`$UseTextFormattingWhenEvaluating = True}, RawBoxes[MakeBoxes[expr]]], "Input", LanguageCategory > "Mathematica"]]
(*examplesthese "almost" work, but the FrontEnd converts to StandardForm 2d form and removes indentation. I'm trying to make it look more like InputForm*)
expressionCell[Integrate[x y^2, {y, 1, 2}]]
expressionCell[ Manipulate[x y^2, {y, 1, 2}] ]
expressionCell[ Module[{x, y, z}, x y z ] ]
(*Method 2, wrap expr in InputForm*)
Clear[expressionCell] SetAttributes[expressionCell, HoldAll];
expressionCell[expr_] := NotebookWrite[EvaluationNotebook[], Cell[Block[{BoxForm`$UseTextFormattingWhenEvaluating = True}, RawBoxes[MakeBoxes[InputForm[expr]]]], "Input", LanguageCategory > "Mathematica"]]
(*examplesthese work, but I am trying to indicate to students what I am typing, and so wish to eliminate the explicit *multiplication, and I'd like to keep my line returns and indentation on the Module example *)
expressionCell[Integrate[x y^2, {y, 1, 2}]]
expressionCell[Manipulate[x y^2, {y, 1, 2}]]
expressionCell[ Module[{x, y, z}, x y z ] ]
This is a follow on question to "Re: Using Defer on Dynamic Expressions?" which was answered by John Fultz and by Mark Maclure on the Wolfram community site.
