[Mac OS X TeX] source specials?

Macdvi 2.5 relies on the scrltx package from CTAN. This package inserts
a special into the dvi at the beginning of each paragraph and math mode.
An option-click in the dvi file takes you to the approximate location
in your source file. Macdvi sends an Apple Event to a supported editor,
asking the editor to open the source file at the requested line. The
Apple Event actually sent depends on the editor. So far it works with
BBEdit in Classis and OS X and with Alpha in Classic.

>>There is a beta version of macdvi 2.5 included with Carbon CMacTeX which implements this on OS X with BBEdit 6.1. See the "Recent Changes" section
>>of the CMacTeX Web Page (http://www.kiffe.com/cmactex.html).
