Of course, it is. I do use emacs mode but have lots of custom mappings and <C-o>
is one of them:
function _-vi-digit-arg
{
emulate -LR zsh
[[ -z "${NUMERIC}" ]] && NUMERIC=0
[[ -z "$1" ]] && num=0 || num=$(( $1 ))
shift
(( NUMERIC=NUMERIC*10+num )) && $@
}
function _-repeat-for-key
{
emulate -LR zsh
local key
read -k key
local -i OLDLLEN=${#LBUFFER} OLDRLEN=${#RBUFFER}
local OLDLBUFFER="$LBUFFER" OLDRBUFFER="$RBUFFER"
(( NUMERIC )) || NUMERIC=1
if ! [[ -z $2 ]] ; then
eval $2
(( NUMERIC-- ))
fi
while (( NUMERIC )) ; do
eval $1
(( NUMERIC-- ))
done
local -i LLEN=${#LBUFFER} RLEN=${#RBUFFER}
if (( LLEN<OLDLLEN || RLEN<OLDRLEN )) ; then
local KILLTEXT="${OLDLBUFFER[LLEN+1,-1]}${OLDRBUFFER[1,OLDRLEN-RLEN]}"
zle copy-region-as-kill "$KILLTEXT"
fi
}
function _-vi-delete
{
emulate -LR zsh
local key
read -k key
key=$(( #key ))
if (( key==##t )) ; then
_-repeat-for-key 'RBUFFER=${(S)RBUFFER/#$key*$key/$key}' \
'RBUFFER=${(S)RBUFFER/#*$key/$key}'
elif (( key==##T )) ; then
_-repeat-for-key 'LBUFFER=${(S)LBUFFER/%$key*$key/$key}' \
'LBUFFER=${(S)LBUFFER/%$key*/$key}'
elif (( key==##f )) ; then _-repeat-for-key 'RBUFFER=${RBUFFER#*$key}'
elif (( key==##F )) ; then _-repeat-for-key 'LBUFFER=${LBUFFER%$key*}'
elif (( key==##d )) ; then zle kill-whole-line
elif (( key==##$ )) ; then zle kill-line
elif (( key==##\^ )); then zle backward-kill-line
elif (( key==##0 )) && [[ -z $NUMERIC ]] ;
then zle backward-kill-line
elif (( key>=##0 && key<=##9 ))
then _-vi-digit-arg $(( key - ##0 )) _-vi-delete
fi
}
function _-vi-ctrl-o
{
emulate -LR zsh
local keystr
read -k keystr
local -r keystr
local -ri key=$(( #keystr ))
if (( key==##A )) ; then zle end-of-line
elif (( key==##$ )) ; then zle end-of-line
elif (( key==##I )) ; then zle vi-first-non-blank
elif (( key==##d )) ; then _-vi-delete
elif (( key==##0 )) && [[ -z $NUMERIC ]] ;
then zle beginning-of-line
elif (( key>=##0 && key<=##9 ))
then _-vi-digit-arg $(( key - ##0 )) _-vi-ctrl-o
#elif (( key==##s )) ; then zle sedsubstitute
#elif (( key==##= )) ; then zle tailfor
else
zle ${${(z)$(bindkey -M vicmd $keystr)}[2]}
fi
}
zle -N vi-ctrl-o _-vi-ctrl-o
bindkey -N evi emacs
bindkey -A evi main
bindkey -rM evi "\C-o"
bindkey -M evi "\C-o" "vi-ctrl-o"
