I've compiled and installed 'tth' within visibility of path. Then compiled and installed LyX 1.1.2. (Configure reported that it found tth.) Was there anything more to it? When I do "Export as HTML", the file gets written as .tex. In the terminal window, from where I ran LyX I see a header of an html document... Like this: ,----- | main:~/$ lyx | Unable to open keymap file | <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" | "http://www.w3.org/TR/REC-html40/loose.dtd"> | <HTML> | <META NAME="GENERATOR" CONTENT="TtH 2.55"> `----- If run by hand, tth converts the .tex file just fine.
