Thanks Bart, I'm not sophisticated enough yet for this sort of thing. 
Where do I put this function? I'll certainly play with it, but I've not

are a mystery. Is there some recommended doc? It's time I knew what 
those dozen or so 'zstyle' lines did.

As to:

I'm guessing this is going to depend on which variable you're trying.
Some variables are autoloaded from modules and appear when you reference
them with $varname, but wouldn't be around yet to be completed when you
first attempt it.

The variable is $t[?] where '?' is the number of each open terminal, and 
which holds the current directory for each open terminal. It's updated 
automatically within 'chpwd()'.  So 'cp $t1/filename .' copies  
'filename' from whatever is the current directory on terminal #1 to the 
current directory on whatever terminal the command is executed from. It 
works fine except that it won't expand on the command line in a brand 
new shell. Note this is not much of an issue since there's no problem 
with the actual copy, only with expanding it visually with TAB, and that 
only becomes an issue if I'm wanting to complete a filename in the same 
command in which a variable also exists, so it's the most minimal of 
bugs. Still it seems to me that it should expand. Actually, any command 
at all prior to the command in which  I attempt this sort of expansion 
solves the problem so it's only happens with an absolutely virgin shell. 
Not worth any trouble.
