The following seemed to work (4.3.10)...


zle-line-init() {
  if [[ -n $ZLE_PUSH_STRING ]]; then
    zle -U "$ZLE_PUSH_STRING"
    unset ZLE_PUSH_STRING
  fi
}
zle -N zle-line-init
alias d="ZLE_PUSH_STRING=\$'cd -\\C-i'"


This causes it to preload the string into the line editor as a string of
characters at the start.  They have to be raw characters to make the tab
active; that's the simplest way I found of doing it.  There are no doubt
entirely different ways of geting a similar effect.
