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?
