[NTG-context] defected by simple stuff - agane

Hi All.. In the charts module you can set a whole cell to be a hyperlink \destination {url(http://www.talkphysics.org)} So what can I write to link to a local file? Along the lines of… \destination {url(file://XXX.pdf)} …where the pdf is in same directory as the file containing the target… This seems as if it ought to be kind of simple, but also seems undocumented… Thanks Ian
