The clickin etc keys concern events, so it must be something JavaScript
and not some named action. So, you have to use javascripts here.  

You can take a look at java-fil.tex, which shows you how to print only
the current page or a page range.  That file also shows you some tricks,
like logical references (you can change the meaning halfway a document)
and the feature that context automatically picks up function definitions
from preambles. Saves some typing.

(I'm not sure what you mean, but beware of tricky undocumented pdf
things.)
