Assuming a half second timeout, then the following should allow jj to work
like escape. Note that the space is needed before -1 to prevent it from
being treated like the :- operator.
====================cut here==============================
float ed_s=0
function jj
{
if [[ ${.sh.edchar} == j && ${.sh.edmode} == $'\e' ]]
then if [[ ${.sh.edtext: -1:1} == j ]] && (((SECONDS-ed_s)<.5))
then .sh.edchar=$'\b\e'
else ((ed_s=SECONDS))
fi
fi
}
trap jj KEYBD
