Yes, thanks. But I released I was hoping for too much here since
region/mark etc works so many different ways depending on settings. As
"dim" in the #emacs said, probably best to rely on C-a C-k. e.g With my
setting hitting right arrow there results in "end of buffer" error.
Thanks for your time though!
