How to Change Font


The default font used by g(Math) is called Computer Modern (Note: The preview image will always be rendered using this font).

 You can change the text font in the Advanced tab by using the command \fontfamily{###} preceding the text you want to change.
 
Below is the default font, Computer Modern:
