Found this AppleScript that takes all of your presenter notes, and pulls them into your clipboard, for easy text only paste into another file.
This is a huge life/timesaver when you want printed notes for a long presentation, since Keynote has no native way of doing this elegantly.
tell application "Keynote"
open (choose file)
tell front document
set presenterNotes to presenter notes of every slide as text
set the clipboard to presenterNotes
do shell script "pbpaste > ~/keynote-notes.txt"
quit application "Keynote"
