I had finally sat down and configured zsh new completion system to
somewhat my liking, and yes its seems to take a lot of trial and
errors to get the behaviour one wants.
My configuration I think does the 3 things that you mentioned:
1. If there is single match, it just inserts
2. If there are more then 1 match, it adds the common prefix, then stops.
3. If you press TAB one more time, menu selection is entered, where
you can use arrow keys to select the match, Enter keys exits selection
_and_ executes the command line
4. While at menu selection you can press ^Z or Alt-backspace, which does
undo, and brings you back to step 2, with the common prefix displayed.
5. If you press Tab on a glob pattern, then the selection menu offers
all the files matching pattern as the first choice, followed by each
file matched by pattern individually, ex:
gives menu selection of items
/usr/sbin /usr/src /usr/share
6. Unambiguous matches on a glob in the middle get inserted immediately:
cd /usr/s*/lo*/zsh<TAB> gets expanded
7. Ambiguous matches on a glob in the middle enter menu selection:
Enters menu selection with: /usr/src/local /usr/share/locale and
/usr/s*/loca (orig string)
# control the menu completion with zstyle
setopt no_menu_complete nolistbeep
# ksh like binding
bindkey -M viins "\e\\" complete-word
# without this everything gets mixed up for _expand
zstyle ':completion:*:*:*:*' group-name ''
zstyle ':completion:*' completer _expand _complete _match _correct _approximate
# below may need adjusting, if you type ae<tab> it gives bad results
# giving you all 2 letter commands
zstyle ':completion:*' max-errors 4 not-numeric
# I never seen this prompt, where should it appear?
# corrections still work, ie cd /u/l/s/zsh<Tab> works
zstyle ':completion:*' prompt 'Made %e corrections'
zstyle ':completion:*:expand:*:*' tag-order 'all-expansions expansions'
zstyle ':completion:*:*:*:*' group-order all-expansions expansions
# this enables menu completion, but on the 2nd tab only
# select without =1 does not work the same way
zstyle ':completion:*:*:*:*' menu select=1
zstyle ':completion:*:*:*:*' verbose yes
# without below glob in the middle does not work
zstyle ':completion:*:*:*:*' list-suffixes yes
# Alt-backspace to undo
bindkey -M menuselect "\M-^?" undo
bindkey -M menuselect "^Z" undo
# Incremental search forward and backward like in emacs
# (requires stty -ixon)
bindkey -M menuselect "^S" history-incremental-search-forward
bindkey -M menuselect "^R" history-incremental-search-backward
bindkey -M menuselect "^N" vi-insert
# shift-tab go backward
bindkey -M menuselect "\e[Z" up-line-or-history
bindkey -M menuselect "^@" accept-and-infer-next-history
# Make enter exit menu selection and do actual command
# instead of just exiting the menu selection
bindkey -M menuselect "^M" .accept-line
# sort files by date and follow symlinks
zstyle ':completion:*:*:*:*' file-sort date follow
# I like my Esc/ search very much, put it back
bindkey -rM viins "\e/"
Hopefully this helps,
