Screen - switch tabs in subscreen

Question

I use this in my .screenrc:

bindkey ^[q prev
bindkey ^[w next

to switch between windows with alt+w/q If I open screen in screen, I can switch like: ctrl+a+a + number, but I would like to id for example with: alt+a/s

Is it possible? Thank you

Well. As far as there is no if statement in .screenrc syntax, we should use shell. Assuming your shell is GNU Bash, you can put this in the .bashrc

case "$TERM" in
    screen*)
        [[ $PARENTTERM == screen* ]] && {
            screen -X eval 'bindkey ^[s prev' 'bindkey ^[a next'
        }
        ;;
esac

(case "$TERM" in block must already exist)

And this in your .screenrc:

setenv PARENTTERM "$TERM"

So ^[a / ^[s will be bound in every Screen, starting inside other Screen. There is no need to unbind ^[q and ^[w but you can do it.
