How to change font in the macro editor?

I started to write makros. The Markoeditor looks a litte small for me and I wantet to change the size of the written text.
I tried Ctrl+ + or Ctrl + Sctolling with the mous, but nothing changed. Also in the Options i didn’t find anything to change the fontsize or the font itself.
Can anyone help me or give me a hint?
