Thank you SO MUCH! This is exactly what I was looking for!
The link to the zip file is now broken.
Apart from that, have you updated the code since 2006? There are some issues with Visual Studio 2010. (it inserts extra RTF junk not stripped by your macro, and extra indentation is not removed)
If you’re looking for the download, there’s a modified version of the code on http://coleman.jandasoft.biz/?p=32 - it has an additional macro, but is otherwise the same.
