The different processors need some different LaTeX output. The most visible ones are that XeTeX and LuaTeX need utf8 always, usually use fontspec for the non-tex fonts (and then no inputenc and fontenc) and use polyglossia instead of babel. XeTeX and LuaTeX are quite similar currently, this this might change with LuaTeX's further development. > 2. We offer the export format "LyX" but that does obviously nothing and is > confusing. What is it for? We need it to export from LyX to anything. I suppose it's only useful in the export dialog if you use the "send to" feature (i.e. enter a command in the dialog's lower widget). > 3.

You can make a DVI (and PostScript) with LuaTeX and all its features (non-tex fonts, real unicode etc.). > 5.

AFAIU "DraftDVI" is the normal DVI output, as produced by LaTeX, on Windows (this export format does not exist on other OSes). Then we process this file with a clean_dvi script to the final "DVI". This postprocessing seems to be necessary on Windows to handle special chars in paths etc. See http://wiki.lyx.org/LaTeX/FilesWithSpecialChars. > 7. What does the menu Navigate->Forward Search?

If you enable forward search or "synchronize with output" in Document > Settings, this menu item navigates the ouput file (DVI, PDF) to the place where the cursor in the LyX window is. I think this feature is already documented. HTH, Jürgen
