It is interesting that - again - there is a helpful function (HelpLookup) which is not documented. At least searching for it doesn't turn up any results in the Documentation Center. I have a question: Considering my code as well as Fred's code, I wonder if there is an easy way to change the style of a cell (programmatically). In my code for the Mathematica Book I use some sort of hack, and Fred's version is rather complicated as well, although it at least looks like sound programming. What I expected to work (but it doesn't) is something like SetOptions[<cell to change>,CellStyle->"newstyle"]; NotebookWrite[nb,<cell to change>] But that sort of code prints the cell in its old style. If you look at the InputForm of the newly printed cell, it has CellStyle->"newstyle" as an option, but that doesn't do anything apparently, since "oldstyle" is still the second argument of Cell[...]. Any ideas?
