Re: [NTG-context] math: \text does not scale properly
Hi Alan, thanks for your help. That's indeed an option, but not much of a difference to using \normal I suppose. In addition, \text has the nice feature of preserving the space character, which makes it very useful for lazy people (of course I can add \, and friends but...).
