That may be what I was looking for. I overlooked the folder, I suppose, 
because it had the nondescript name "default" ... but there's a lot of other 
interesting stuff in there. I might get lost, and may wish to experiment with 
modifications of some other programs and services. 

All the web pages I searched pointed to those other two locations, but they 
didn't solve the problem. I'll report on my results. 

Thanks much!
