[racket] Increasing the font size of slideshow's commentary window

I'm using the slideshow program to make some slides and I was wondering if it was possible to increase the font size that is used in the commentary window. I must be getting old because I have a hard time seeing my comments when I'm a few feet away from my laptop. I'm using version 5.1.0.2--2011-02-01(aed0980/g) [3m], from git but can up/down grade if needed.

Thanks,

P.S. Thanks for saving me from PowerPoint death.
