 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!<br><br>The TeXbook by Donald E. Knuth <a class="moz-txt-link-freetext" href="https://amzn.com/0201134489">https://amzn.com/0201134489</a><br>Programming
