Except perhaps the documentation. I have yet to find a reference that clearly describes what \rm is to do in ConTeXt. One responder pointed to http://www.pragma-ade.com/general/manuals/cont-eni.pdf. The closest thing to a definition of \rm there that I could find is on p. 111: "The command \rm is used to switch to a roman/serif/regular style,..."
In his first reply to your message, Aditya posted the link to the new manual chapter on "Typography". This chapter and the following one "Fonts" are planned to be the definitive answer to all questions regarding fonts and font selection in ConTeXt. If you believe the text could be improved even further beyond the changes already made compared to the manual at Pragma ADE, please tell us how (for sure, the meaning of the macro \rm is not going to change!). We all want the manual to be as good as humanly possible, but it is often quite hard to write at beginners' level when you have advanced past that point yourself. If you can find a good (or at least better) way to express what \rm,\ss,\tt,\hw and \cg do compared to the current prose in co-typography, please post it. Just keep in mind that the manual has to remain independant, so texts that presuppose knowledge of plain TeX and/or LaTeX are not acceptable except as a side/footnote. Best wishes, Taco
