I frankly don't know if it exists with all distributions and you don't state what you use, but I recently found out that my WinConTeXt includes a stand-alone version of TeXShow, which is very hand for this kind of use - and I think the program is more up to date than any paper manuals; the developers will be able to tell, if they make a new one for a new distribution of ConTeXt or just occasionally. Searching for file texshow might find yours (no luck on my Mac...); the online version is at http://texshow.contextgarden.net/
The standalone texshow is by me. It is a perl/Tk script, so if you have a proper perl+Tk installed on your system, you should be able to run it. Both the texshows: Patrick's web version and my standalone version are always up-to-date with Hans' XML files. By definition, since they use the XML files as their primary data source (barring errors or omissions in the XML files, of course).
THIS might be what you were asking for: There's a "quick reference" file that can be handy as augmentation to other manuals: http://www.pragma-ade.com/show-man-10.htm or, if your preferred language is English, directly here: http://www.pragma-ade.com/general/qrcs/setup-en.pdf - at least the English version is *very* new, dated on March 19, 2007, so it should be quite up to date [probably too up-to-date for my old ConTeXt distribution...].
I am do not know if the qrcs are always up-to-date, but I know they are periodically regenerated by Hans himself, using those same XML files as source. Best, Taco
