short titles in headers, but not in TOC

[Pedro Tejedor]

Hello LyXers,

I have a document with fairly long titles of chapters. I am using 
koma-script report, and fancy headers. Some of the titles don't fit in 
the header of the page. If I use the insert->short title, this one is 
used in headers, which is good, but is also used in TOC, which is bad 
for me.

żis there a way to use the short titles only in headers, but not in TOC?

thanks,

Pedro
