You can get at least some of the effect of that using the new zle
widget code available from 3.1.2. The hard bit is overloading the
cursor keys so that they still work as normal, I haven't tried that.
However, the following (using ^x^n and ^x^p) will insert previous or
subsequent directory entries on the command line, and if you have
AUTO_CD set hitting return will take you there. You may want either
to set AUTO_PUSHD as well, or to make the shell insert a 'pushd'
before the directory name (change the BUFFER= part), or the cd will
wipe out the first entry in the stack.
Note that these functions will simply wipe out anything on the command
line when called. Some test like '[[ -n $BUFFER ]] && zle push-line'
might be sensible.
(( dir_no )) || dir_no=1;
[[ $((--dir_no)) < 1 ]] && dir_no=$#dirs
(( dir_no )) || dir_no=0;
[[ $((++dir_no)) > $#dirs ]] && dir_no=1
zle -N show-next-dir
zle -N show-prev-dir
bindkey "^X^p" show-prev-dir
bindkey "^X^n" show-next-dir
