Hi Dj, I took your advice and tried another Listnener, and, I'm pleased to say, I managed to finish (Including 'Highlighted word' and the word to be written at the bottom. That said, once again this is at the 'easy' end of the scale, still, I'll take it.
I only have access to the online Chambers and it's not given in that, but I did manage to find another reference that gave it as term used in printing, so I'm happy. Thanks again and thanks Ginge.
