Thanks Kornel,

Before making a move like that, I'd need to see some documentation
spelling out exactly how to do it. There are many different definitions
of "copy a line"; where, in what context, etc. I already spent 6 hours
getting past this problem, and I don't want to spend another 6 because
I blew up my LyX system doing the wrong thing.

Thanks,
