numbering paragraphs (lyx newbie)

[Yamandu Ploskonka]

Hi!

I've been into Lyx for several weeks.
Nowadays trying to comply with these specs:

"It is desirable to include an indentation at the beginning of each new 
paragraph, and for paragraphs to be numbered (i.e., [0001], [0002], 
[0003], etc.)."

Despite already 2 days searching everywhere, the best I came up with was 
an ugly kludge. There /must/ be a better way

   \renewcommand\thesubsubsection{{[000}\arabic{subsubsection}{]}}


this, used with a local article.layout where I make


DefaultStyle Subsubsection

   Style Subsubsection

       Margin Dynamic
       LatexType Command
       LatexName subsubsection
       Font

           Family Roman
           Series Medium
           Size Normal

       EndFont
       TocLevel 1

   End


then eventually ERT with 
\renewcommand\theparagraph{{[010}\arabic{paragraph}{]}


It works, *except* for the PDF output of my "subsubsections" being in bold

I have absolutely not been able to fix that, except manually, and then 
the numbering stays in bold...

can you help, please?

Thank you!
