What I was going to say as well, but thanks for introducing
copy-prev-word to me, as I was wanting that functionality but hadn't
found it earlier.

Like Vim does it.  I have only one binding for these:

bindkey "^X^L" history-beginning-search-backward

That's also how Vim does it, in insert mode.

My most useful binding is

_sudo-command-line() {
  [[ $BUFFER != sudo\ * ]] && LBUFFER="sudo $LBUFFER"
}
zle -N sudo-command-line _sudo-command-line
bindkey "^Os" sudo-command-line

as I always forget to add a sudo...

Here's my version of a command like that:

~/.zsh/functions/d:

# contents: d command.

emulate -L zsh

autoload -U colors

local color=$fg_bold[blue]
integer i=0
dirs -p | while read dir; do
  local num="${$(printf "%-4d " $i)/ /.}"
  printf " %s  $color%s$reset_color\n" $num $dir
  (( i++ ))
done
integer dir=-1
read -r 'dir?Jump to directory: ' || return
(( dir == -1 )) && return
if (( dir < 0 || dir >= i )); then
  echo d: no such directory stack entry: $dir
  return 1
fi
cd ~$dir

I don't know how iselect works, but this works very well for me.
