Nathaniel has described the configuration variable that is to be changed in the Aquamacs change log, which comes with Aquamacs 2.0.    (He has also commented on the mailing list in detail.)

Well, then I must not be terribly bright or we understand different things by "very easy". :-)  I have gone through this thread and I think I've found the instructions in question from Konrad (not Nathaniel, as a follow-up pointed out) here:

Am I to understand that I need to go in and make those changes to tex.el?  And then select the "Skim" option for "output pdf" under "Tex View Program Selection"?  I have tried doing the latter only, and now Ctrl-c Ctrl-c brings up the View command '(aquamacs-call-viewer 27 "worlds.tex")' -- needless to say, it doesn't do anything.  So apparently I do need to make the changes in question to tex.el, but somehow it seems to me that things should indeed be easier.

I've been using Aquamacs 1.9 and MacTeX 2009 but just upgraded to Aquamacs 2.1 and MacTeX 2010, which led to my current difficulties.
