I was thinking about this. Latex (at least in tetex 1.0.7+20011202) has t5he option -src-specials, which puts a "source special" at the end of each line in the latex source. So I think that two approachs are possible: 1. lyx invokes latex with the option -src-specials. In this case, lyx has to have some function like goto_latexline that would take one argument, so that 'goto_latexline n' would leave the cursor in the place of the lyx view that generates the nth latex output line. The simple way to do this is to generate the latex output counting its lines each time goto_latexline is called. 2. Lyx itself inserts "source specials" at convenient points, and has the function 'goto_srcspecial', so that 'goto_srcspecial n' would be equivalent to a search in the lyx buffer. Option 1 would involve a good policy in breaking lines in the latex output; option 2 would involve good policy in inserting the "source specials". Another much useful feature that could be achieved with source specials is to show the dvi preview at the page where the cursor is in the lyx view. Regards, Joao.
