Hi, I seem to have mis-edited the Wiki, specifically I have changed the Bibtex.sidebar (https://wiki.lyx.org/BibTeX/SideBar) instead of adding to the BibTex page itself. Further to my embarassment, I don't seem to be able to reverse my edit. Sorry!! If anyone else knows how to and can reverse the change, I would be grateful. Best regards, John Beattie
