Slideshow still lacks some features I'd want -- the ability to display
in a window instead of full screen, and the ability to toggle between
the two with a keystroke. Also, having embedded math is nice (I'm
exporting LaTeX seminar). Finally, I need to have DrScheme installed
on the presentation machine, which isn't always easy -- it would be
nice if Slideshow exported PostScript or PDF.

That does wonders. Thanks.

I'm running a Makefile to do the slide generation, and it runs a
script which calls mzscheme. If that reports an error, I open the
slide source file containing the error. I know the offending line
number and column, but I don't know a quick way of getting there --
something like M-x goto-line in Emacs. 

Another thing that frequently happens to me is that I forget a close
paren. The whole source file turns pink, which is not much use to
me. There isn't a key shortcut for "clear error highlight", so I have
to do that from a menu before I do anything else. Then I go down to
the bottom, stick my cursor on the last close paren, and scroll up to
find out what it's closing, which generally is quite close to my
error. Is there any more effective way to do this? Thanks. --PR
