} This is cool.  But what options are necessary in order to make this
} work?  The commands above produce this output for me:
} 
}   Some
}   text
}   [particular
}   text]
}   Another
}   text

unsetopt shwordsplit

or place each of the $txt[...] in double quotes:

print -l "$txt[1,$txt[(i)\[]-2]" "$txt[(r)\[,(R)\]]" "$txt[$txt[(I)\]]+2,-1]"

You'll find that many examples posted to zsh-users assume that arrays are
superior to strings-automatically-split-at-spaces, and therefore assume
that you're using the default zsh setting of no_shwordsplit.
