Hi Jan,
unfortunately, these commands are in no book. I just looked them up in the ConTeXt source. However, these two books helped me a lot in improving my understanding of TeX and ConTeXt. They are definitely worth their money!
The TeXbook by Donald E. Knuth https://amzn.com/0201134489
Programming in Lua by Roberto Ierusalimschy https://amzn.com/859037985X
Kind regards,
Henri

>> The inner workings of this solution are quite messy. You *have* to have the \NC\NC between text and formula and the formula must not contain any further alignment points; text has to be enclosed in \rlap. As you can see it centers the formula unconditionally and just flows into the text if it doesn't fit. Just don't do it like this.
