Like you, I was constantly frustrated by the seeming difficulty of
inserting an end-of-frame marker to the end of a slide. I didn’t find
it intuitive at all. However, after much use, it has now become second
nature.
What I seemed to discover is that the secret (if that’s the right
word) is to place the cursor at the bottom of the current frame in an
**unnested** and content-free environment and then hit <enter>. It
seems to work best if the unnested, empty environment is “standard,”
but it also works for me if the environment is “itemize,” which it
often is in my Beamer presentations. As I love keystroke combinations,
after composing the last bullet point of a slide (“frame” in
Beamer-speak), I hit <enter> to obtain an empty environment. I then
hit <shift><tab> as many times as necessary to remove any nesting. I
then hit <enter> and, voila, an end-of-frame marker appears.

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.
