I didn't know about whizzytex, it's very interesting. The ability to modify placement with the mouse looks quite neat. I'll look into it, thanks. To add on pcm

I didn't know about whizzytex, it's very interesting. The ability to modify placement with the mouse looks quite neat. I'll look into it, thanks. To add on pcmonk's answer, this program has two advantages over latexmk : it does not require the user to save the file (in the video, you can see the double stars in the status bar of emacs : the file is not yet saved) and it works with any text file-(compile)->result loop, not just LaTeX. You could use it to edit executable code (see the python example) or HTML for example.
