Perhaps I am missing something obvious, but I cannot get this to work. I
tried applying your suggestions, and ended up with this:

_list-result() {
    print In _list-result
    local -a hlist=($HOME/*)
    compadd -n -V list_result -M 'l:|=* m:{[:lower:]}={[:upper:]}' -- $hlist
}

zle -C list-comp menu-complete _generic
zle -C rev-list-comp reverse-menu-complete _generic
zstyle ':completion:*list-comp::::' completer _menu _list-result
bindkey '\ee' list-comp
bindkey '\eE' rev-list-comp

However, something is missing, because completion is not  triggered. In
fact, the debugging line "In _list-result" is not printed, so _list-result
is never called. I assume there is something more that I need to put in
place that I have missed?
