Hi Gerald, thanks so much for your enlightenment. The '-m' option
seems to be the key to nested sessions.

Below are my configurations (snippets) that I'd love to share
with you:

escape \377\377         # disable C-a
bindkey -k k6 command
bind c screen screen -m -c $HOME/.screen.sub.rc
screen 0 screen -m -c $HOME/.screen.sub.rc

escape \377\377         # disable C-a
bindkey -k k7 command
bindkey -k k8 prev
bindkey -k k9 next

With function keys k6, k7, k8 and k9, I'm able to switch very
conveniently between sessions and windows within nested sessions.
To create a new session, I press f6 and c; to create a new
window, I press f7 and c; to switch to the next window within the
same session, I press f9; to switch to the next session, I press
f6 and n, and so on.

I also considered to use Ctrl-Alt-Left/Right keys, but it seems
they are not distinguished from Left/Right keys, or at least
under linux console terminal. So finally, I give them up.

Thanks again for your kind help,
