Thanks jford.

If I am seeing things correctly, it appears that styles aren't actually copied
into user categories. Only one copy is in the bb folder (where the styles are
normally stored). The user categories only contain a reference to the actual style.
So you can't really delete them anyway. They also disappear from the user category.
What I was intending to do was delete the style from the main list if I didn't use
it, but also delete a style from the main list if I had it in a user category. In
other words, as if it were moved and not copied (effectively).

I also intend to keep a full set of the styles, for as you said, I might want them
one day. I could just keep them all in a folder and copy one in as I need it, much
like adding new styles (if it's possible to simply do it that way).
That is my current idea, and what I used to do with a much earlier version.

But noting the styles I want to remove and then finding them in the bb folder is
pretty tedious. And finding and/or restoring the styles in the bbw.lst file is even
worse (that thing is huge).

I was hoping for a solution that was similar to moving files around in windows.
