The following code highlights the matching symbols when you type them.
Unless I'm mistaken, it was originally written by Oliver Kiddle.

function highlight-paren()
{
    local i nested=3D1

    typeset -A match

    match=3D(
        \) \(
        \] \[
        \} \{
        \" \"
        \' \'
        \` \`
     )

    zle self-insert

    for ((i=3D$((CURSOR - 1)); i; --i)) {
        [[ $BUFFER[$i] =3D $match[$KEYS] ]] && (( ! --nested )) && break
        [[ $BUFFER[$i] =3D=3D $KEYS ]] && (( ++nested ))
    }

    region_highlight=3D("$((i-1)) $i standout")
    zle -R
    read -kt 1 && zle -U "$REPLY"
    region_highlight=3D()
}
zle -N highlight-paren
