I can't get it to work Mikael, here's my current hacked up test code, I 
source it in two different terminals and then change focus between them 
but nothing seems different.  I've tried a few variations on this with 
no luck:
------------------------------


#!/usr/bin/zsh

function _zle_line_init()
{
   [[ $TERM = xterm ]] && printf '\e[?1004h'
echo in-$TERM
}

function _zle_line_finish()
{
   [[ $TERM = xterm ]] && printf '\e[?1004l'
echo out-$TERM
}

zle -N zle-line-init _zle_line_init
zle -N zle-line-finish _zle_line_finish

# The test echo's in the functions show that the above two lines are in 
effect, I get:

#    $ in-xterm
#    out-xterm

# ... after every ENTER.

bindkey '^[[I' focus-in
bindkey '^[[O' focus-out

zle -N focus-in _focus_handler
zle -N focus-out _focus_handler

# But this seems not to be called:
function _focus_handler()
{
   if [[ $WIDGET = focus-in ]]; then
     zle -M "hey we got focus"
   fi
   if [[ $WIDGET = focus-out ]]; then
     zle -M "we lost focus"
   fi

echo _focus_handler where are you?
}

echo sourced ok
