I can only think of one, but it's probably too annoying to use:
bindkey -s 'd^M' $'cd -\x09'

There are two problems here:
1) you need to hit enter pretty quickly.
2) there will be a slight pause after every d you type before it appears.

Actually that's a lie, you can do something up like this too
zle -N accept-line my_accept_line_wrapper
function my_accept_line_wrapper() {
  if [[ $BUFFER = d ]]; then
    zle -U $'cd -\x09'
    #doing the above sequence by putting the text in $BUFFER and calling
    #zle expand-or-complete doesn't work, the cursor is in the wrong position
    #setting $CURSOR to 4 doesn't seem to help, nor does zle end-of-line
    zle .$WIDGET
