I am coming back to using ConTeXt after a relatively long hiatus, so I am trying to re-learn old things and learn the new stuff. Please bear with me. I want to use OS X's Helvetica Neue Light in a document. How may I do that? I have tried: \definefontfamily [myfamily] [serif] [Helvetica Neue Light] but, fair enough, that results in `font with asked name 'unknown' is not found`. If I use \definefontfamily [myfamily] [serif] [Helvetica Neue] then the document is typeset in Helvetica Neue, but in boldface. Why? Using mtxrun, all the relevant files are found: mtxrun --script fonts --list --all --pattern=neue* helveticaneue helveticaneuebold /System/Library/Fonts/HelveticaNeue.dfont index: 13 helveticaneuebold helveticaneuebold /System/Library/Fonts/HelveticaNeue.dfont index: 13 helveticaneuedeskinterface helveticaneuedeskinterfaceregular /System/Library/Fonts/HelveticaNeueDeskInterface.ttc index: 9 helveticaneuedeskinterfacenormal helveticaneuedeskinterfaceregular /System/Library/Fonts/HelveticaNeueDeskInterface.ttc index: 9 helveticaneuedeskinterfaceregular helveticaneuedeskinterfaceregular /System/Library/Fonts/HelveticaNeueDeskInterface.ttc index: 9 How do I specify the font's weight?
