... can I simplify that?  I only ever want to search for completion of 
files (or directories) in the current directory and the listing of 
matches shown below the CL seems ... well, I dunno, maybe it can be used 
in some way?

Here's my completion config, it's a complete mystery to me:

zstyle ':completion:*:default' list-colors ${(s.:.)LS_COLORS}
zstyle ':completion:*' auto-description 'specify: %d'
zstyle ':completion:*' format 'Completing %d'
zstyle ':completion:*' list-prompt %SAt %p: Hit TAB 'for more', or the 
char to insert%s
zstyle ':completion:*' select-prompt %SScrolling active: current 
selection at %p%s
zstyle ':completion:*' completer _expand _complete _files
zstyle ':completion:*' matcher-list '' 'm:{a-z}={A-Z}' 
'm:{a-zA-Z}={A-Za-z}' 'r:|[._-]=* r:|=* l:|=*'
zstyle ':completion:*' verbose true
zstyle ':completion:*:match:*' original only
zstyle ':completion:*:approximate:*' max-errors 1 numeric
zstyle ':completion:*:expand:*' tag-order all-expansions
zstyle ':completion:*:cd:*' ignore-parents parent pwd

... I take all edits and suggestions on faith.  Simpler is better.
