[NTG-context] cite-specific question

Hi, in LaTeX I've been able to do cites in a number of different ways, depending on what's needed. In ConTeXt I've figured out how to do \cite[key] Full author list and year (Watson and Crick 1953) as well as how to add reference to the page number using \cite[extras={, page 5}[key]. But I'm wondering if it is possible to get something similar to \citeN{key}, \citeNP{key}, etc. in LaTeX: \cite{key} Full author list and year (Watson and Crick 1953) \citeA{key} Full author list (Watson and Crick) \citeN{key} Full author list and year. Watson and Crick (1953) \citeyear{key} Cite year only (1953) All the above have an NP variant without parentheses; Ex. \citeNP. Thanks, Trond
