Hi Dimitris,
I cite from mg64218 (Feb 7, 2006), thread "Notebooks, packages, cells, and
literate programming":

"One alternative way to enter inline comments, if you anyway want that, is
to wrap them up in a ordinary Mathematica function in this way:

Comment[" This is my comment. "];

There usually are any number of places in the code where you could add
comments in this way. If you have not defined the function Comment, the
statement will not be evaluated. Such comments are not removed by
Shift-Ctrl-N or Shift-Ctrl-I.
Of course I must here also remind that the button "CopyAsInputForm" in my
SetFaceAndFont Palette preserves (* *) comments by converting them into the
suggested alternative. (See http://web.telia.com/~u31815170/Mathematica/)"

The palette is not updated to version 6 yet, since I just have had
Mathematica 6 available a few days, but this feature seems to be
functioning.

Best regards

Ingolf Dahl
