Re: creating input cell with unevaluated expression?
Aaron, In Mathematica 4.0, your second idea works perfectly, StylePrint[Unevaluated[1+1],"Input"] In Mathematica 3.0, it doesn't. I Traced the above function, and came up with a potential workaround, which is to give StylePrint the attribute HoldAllComplete. This may not be a very wise thing to do, however, so caveat emptor I guess. Anyway, first execute SetAttributes[StylePrint, HoldAllComplete] and then try out your second idea.
