I found it!

How does one change the font from the default lucon.ttf? I tried picking a different fond and I get back this error:

Internal IDE error

You have to point to the file itself, wherever it might be on your hard drive, rather than just type its name.  (Especially if you're on Linux/Mac, as they do zero searching for a file.)

For example:   cour.ttf <-- this won't always work.

C:\Windows\Fonts\cour.ttf   <-- this will.
