Google-docs – Is it possible to make letters upright (non-italic) in equations in Google Docs

google docsgoogle-appstext formatting

On this forum answer on Google Docs it is mentioned that commands such as \mathrm{} should be possible. Just like in regular LaTeX (or MathJax).

I cannot make this command work on my page, though. Other simpler commands such as \frac, \sqrt and \alpha work and are shortcuts for the menu buttons. But the \mathrm (and also not \text and others I've tried), which should make the text upright, does not work and there is no roman ('non-italic') button in the equation menu.

So, I guess the question is two-fold:

Why don't the shortcuts mentioned in this forum answer work for me?
And what is a method to make non-italic symbols?

I don't think you can do it for normal text, but \cos and \sin work
