Line used to separate text sections in email

[Anglepoise]

I use Outlook 2003 and received an email from someone using same system. The
email I received was written in several sections and to separate each section
was a black bold line spanning the email, as if underlining the text above.

The lines are neat and make the email very clear; you can't click on them to
get the little 'handles' though, so they weren't manually drawn / autoshapes.
They're all the same length and extend only as far as the text does on
either side of the email, and it's difficult to do that manually...

If you resize the window, the lines resize too and become shorter or longer
as appropriate. It’s like some kind of ‘break’ but I can’t see how they've
been inserted?? I don’t think the sender would have time to do anything
really fiddly with tab stops or anything, so can’t imagine it’d be that?! If
you click the show/hide punctuation button, there’s a new paragraph either
side of the line, but that’s all I can see.

I know this is a bit trivial but it's become irritating! I liked the
clarity of the email and would like to be able to emulate the style, but
can't for the life of me work out how! Could happily forward the email if
anyone wanted to see.

Help - don't want Microsoft to beat me!!

Thanks...

Cracked it - it's key strokes and auto formatting....

Need to type three underscores simultaneously, before hitting the return
button....

Thanks for looking!!

Only available when composing in HTML format. It's called a horizontal
rule tag (the <HR> element).
