LyX ⇒ Renaming single Appendix

[petergggg]

(I have zero knowledge of programming. I can just about blindly copy/paste text into those little red TeX code boxes, but I don't know what I'm doing.)

I'm trying to sort out the single appendix in my koma-script book. I originally inserted the appendix using Document/Start Appendix Here. I've now unchecked that option and inserted \appendix into a TeX red box just before the start of the appendix. That worked in so far as in the ToC the appendix was then listed as "A. My appendix name". Ideally, I'd like it to read "Appendix" or "Appendix - My appendix name".

I tried pasting \appendix\noappendicestocpagenum\addappheadtotoc instead of just \appendix and that changed the ToC to "Appendices" on one line (with no page number) and "A. My appendix name" on the next line with the correct page number. Is there a simple, non-tech solution to my problem?

I've now found a not perfect but good enough for me solution to this. With the Document/Start Appendix box still unticked I deleted \appendix etc and inserted \backmatter and \addchap{Appendix. My appendix name}.
