[GNC] help increasing size of font in GnuCash?

[Marilyn Graves Kimple]

Is there a way to customize the font size in GnuCash? I do not have an easy time reading screens and I also have arthritis in my hands, which means I need a bigger target for my cursor. I looked at the documentation and all I could find was a style sheet for reports. My built-in Mac tricks for screen reading (control+, track pad motions) do not work with GnuCash.
