Allow copying from presenter notes while in presentation mode

Here's a simple feature request, something that's definitely not supported in the current version of Keynote. It would be convenient to be able to copy text out of the presenter notes while a Keynote presentation is playing.

My use case is teaching programming. The slides show code fragments. I'd like to be able to paste those code fragments into a live IDE and run them. At present, the only way to do that is to stop the presentation so that I can select the code. It would be great to have the text selectable in the presenter notes, in which case I could grab the code from there without stopping the presentation.

Thanks!
