Virgil,
My experience was similar, but I had trouble detecting or deciphering 
what is the nature of the environment my cursor was in-- the screen did 
not magically change to green or somesuch safe color when the cursor 
entered the right environment, so I ended up hitting /enter/, /shift 
enter/, /control enter /etc. until somehow I got to the desired environment.
    I think that your experience confirms my feeling that it shouldn't 
HAVE to be that hard.  OTOH, Chinese, for me, is very difficult, because 
I don't know it, but 1.5 billion Chinese have no trouble with it, so if 
I knew Lyx/Beamer as well as they know Chinese, this thread would have 
never started.
