Yes, sorry.  I'm unfamiliar with formal emacs terms.  What are the 
actual TeX/LaTeX modes called?

I don't see a specific AUCTeX menu, but "F10 l" gives me a LaTeX menu if 
it says "section" instead of "subsection" in the file, and "F10 T" gives 
me a TeX menu if it says "subsection" as written above.  Furthermore, 
"F10 c l" runs LaTeX and "F10 c t" runs TeX correspondingly.  Can you 
confirm this?

Not that I know of.  I looked through my .emacs and didn't see anything. 
 How do I set TeX-default-mode to be LaTeX?

I've never used ConTeXt, presumably I can start caring if/when.  Of 
course, the archives might benefit from a more general solution if there 
actually is one.

Why do I care about this?  I break large documents into several files 
and \input them from the master document file, and so sometimes I end up 
having a single subsection in a file.

Thanks for your help,
Chris
