SUBSCRIPT WITHIN EXPRESSIONS



The following yield predictable results.

In:=   D[a[0] a,a]
Out:= a[0]

I thought maybe the symbol a[0] will look better if I used an 'a' with a
subscripted '0' instead.


But to my surprise the following...

In:=    \!\(D[a\_0\ \ \ a, a]\)

yielded...

Out:=
\!\(\*
  RowBox[{\(a\_0\), "+",
    RowBox[{"a", " ",
      RowBox[{
        SuperscriptBox["Subscript",
          TagBox[\((1, 0)\),
            Derivative],
          MultilineFunction->None], "[", \(a, 0\), "]"}]}]}]\)

How do I get the subscripted 'a' to work as intended ( like the a[0] )?
