I guess you'd want to iterate over all of the frames, via
get-top-level-windows. Find those that implement the
drscheme:unit:frame<%> interface, and then use the get-tabs method to
get the tabs in those frames. From those tabs, use get-defs to get the
definitions text and from that use get-filename to get the filename. To
actually bring a different file to be editing, use handler:edit-file.
(It also works to open new files and open empty windows/tabs if you
pass #f).

the get-tabs method doesn't exist in the 352 or anywhere else for that
matter, until just a minute ago when I added it to the svn version of

It's an easy patch, if you'd rather patch your version of drscheme than
get the svn version. Just look for get-tabs in the svn sources and copy
that one line into your version:
