Thank you. That is what I wanted.

Ahh ok. So bind requires "command" prefix (I have set as F12), and
bindkey is where screen acts like a window manager, "consuming" that
key which has been bindkey'ed, and doing something.

I have XFCE maximise a window on F11, so F11 never gets to screen, and
F12 gets through to screen, but doesn't get to bash because screen
consumes it.

I have set up something simimilar for three levels of gnu screen -
outer, inner1 and inner2. This works well with a quick-to-press key
sequence for screen next and screen prev (I use CTRL-Pgup and
CTRL-Pgdn, like firefox) to cycle through the tabs ("screens" as
screen calls them). Then my inner1 screen uses ALT-Pgup and ALT-Pgdn
for cycling, and F9 for command. Simple to setup really.

The "disable keybind" above will allow me to have my outer screen use
an "inner1" keybinding to open up the inner screen session, and
immediately unbind that key, so it can be used by inner1 screen
session. I need that because I was running out of Fn keys :)

Thanks heaps, very convenient,
