[plt-scheme] Emacs modes and s-expression comments

To disable the extra exit warning, you could also just use the
preferences dialog. See the "warnings" section.

Or, you might have tried reading the manual. Searching for "exit" in
Help Desk and following the link into the DrScheme manual sends you to
the right place.

If you did try searching in Help Desk and couldn't find it, please
share the search keys you tried and I will make those work.

Thanks,
Robby
