Subject: Re: arrays with merge

As ali said, the unquoted key is only an issue if there is a declared
variable, at which point the key becomes whatever is in that variable. (or
if its a keyword of course)

I use the "store the string elsewhere" method.  When creating merge strings
for later use, I either create them using the property inspector, or put
them into a field and set a property to the field.

The other option mentioned is pretty helpful.  Put in an unquoted key, and
set the value of it as a variable.  This can be pretty handy because you can
change which key you want to look at on the fly.
