Thank you for the reply! This solution works well.

Actually the documentation for Notebook[] only contains an example,
but it is not clear that this is the /only/ acceptable syntax, so it
is natural that one starts experimenting. I tried to achieve an
effect similar to simply copying plain text from Notepad, i.e. I did
not want any style information to be associated with the copied text.
I was not sure what style to use with Notebook[{Cell["abc",
"style"]}], so I tried Notebook[{"abc"}] which appeared to work.
(Most probably the style should be "Input".)

How would one use CreateDocument[] instead of NotebookCreate[] and
NotebookWrite[]? (According to the documentation, NotebookCreate[] is
obsolete, and CreateDocument[] can insert an expression into the
notebook right after it is created.)
Is the following correct and equivalent to nb = NotebookCreate[];
NotebookWrite[nb, "2+2"] ?
nb = CreateDocument[Cell[BoxData["2+2"], "Input"]];
