Zoom on "presenter notes"/Keynote?

I like very much Keynote, and I use it a lot since IWork 06. But, I use also "Presenter Notes", but the letters are too small. Yes, I know that I can write with a bigger font. But I don't want that. I want to zoom the text as I do in Pages - I always write with 180% zoom at least. Is there anything like this to be doing in Presenter Notes in Keynote?

Thank you all for your answers!
