I'm using the built-in equation tool in Keynote. Is there a way to change the font used by default in Keynote?
Also, I see that when I try to use text in the equation via \text{} the font is in bold mode. How can I change that?
Note that a relevant Keynote question has been asked here.
As an example for the font change see this picture
As an example for the bold text see the picture which was generated by \Gamma \text{ is fixed}
Note that this question is not a duplicate of this one. All of the options mentioned in the linked question are such that simply add a characteristic to the font (italics, bold, roman etc.) but they do not change the font.
Best Answer
There’s no way to change the default font output of the standard LaTeX editor in Keynote.
There might be a way through changing the editor itself, though of course strictly speaking it wouldn’t be Keynote anymore, more of a customized variant.
So practically, no.
Old Answer (for temporary changes):
Yes
\mathfrak{x=2y} clearly changes the font in Keynote, and Pages as mentioned in the question you linked.
