In a function named 'c'.  It's my one stop shopping wrapper around 
'cd'.  Mostly it offers a zcurses based (thanks Sebastian) selection of 
previously visited directories from a persistent, global directory stack 
, but the code I just added (thanks Bart) now gives me this pseudo 
completion like this:

    8 /aWorking/Zsh/Source/Wk 4 $ c N-  # I could have just pressed TAB 
here to complete.
    Changing to N-functionsWorking ...

    8 /aWorking/Zsh/Source/Wk/N-functionsWorking 4 
$                              7:25AM Wed 30

... So before offering a zcurses selection from the directory stack, it 
now attempts what would be almost exactly the same as:

    $ cd N- [TAB]

... Bart's code just globs " N-* " so " N-functionsWorking " is found 
automagically.  It's sorta better than TAB anyway because there will be 
no mysterious completions.  Also actually using TAB on the command line 
sometimes gives you several possible completions but as I have it, if 
there's only one match it just 'cd's' there, if not, you get the zcurses 
selection window.  (And of course I still can complete using TAB if I 
feel like it anyway, that option remains.)  I quite love my 'c' wrapper, 
life was solitary, poor, nasty brutish and short without it.

So the idea of invoking completion within a function is now a matter of 
curiosity  only.  Still I'm surprised it can't be done.  It's one of 
those things where zsh smartness is hard to turn off.

Here's a real life example of 'c' being elegant.  Where the hell are my 
zsh distribution functions?

   8 /aWorking/Zsh/Source/Wk 4 $ c ,a Functions zsh
   Searching entire system for directories matching:  "Functions" "zsh"
   (case INsensitive, WILD) ...
   Changing to /aWorking/Zsh/Zsh-5.8/share/zsh/5.8/functions ...

   8 /aWorking/Zsh/Zsh-5.8/share/zsh/5.8/functions 4 $   # Sweetly found.
