Thanks, I'm glad you're finding Frotz therapeutic. :-)
I do plan on adding cut and paste but I can't rely on the OS
implementation
because the standard text control doesn't support rich text.
In the meantime, you can work around the missing functionality by
starting a transcript in the game using "script".
Then on the notes screen, tap the page icon at the top and you can
view the transcript and copy and paste from there.
Hope you get well soon.
Regards,
Craig
