Thanks for the quick response! However, when I add it to my .emacs file 
I get the following error upon starting Emacs:

Symbol's value as variable is void: TeX-command-list

This occurs whether I place the command inside or outside 
eval-after-load "tex". I have an append command of the same form as the 
one above inside an eval-after-load statement and it works just fine -- 
doesn't this imply that TeX-command-list is defined at that point? 
Regardless, the error comes up whether I place the setcdr command before 
or after the append command. I looked up setcdr in the docs to try to do 
some troubleshooting, but I got nowhere. As far as I can tell your 
syntax is perfect.

Thanks for your help -- you and Ralf have been very patient with me 
while I try to figure Emacs out.
