Thanks, Stefan. Here's what I tried:

{TC "Part I: The Beginning" \L 1 \n}Part I

I F9 to save it.
My TOC toggles to one line (looks like the TOC code)
When I toggle it back, either my Part one is as it was or still in code form.
I tried toggling to hide code and the whole thing reduces to one coded line again.

What am I doing wrong? I cannot see it. I know this should be simple -- it's only code, but something here isn't allowing it's proper use.

Thanks,
Greg
