I want to adjust my document to have Lucida as main typeface, but with brief passages (a few words at most) in a typeface that has the IPA glyphs like Gentium. I've skimmed the manual and the ConTeXt garden Wiki but I do not yet understand which commands I should use where and with which options to achieve this -- preferably in a concise way. Could someone please explain and point out what most current documentation I should read and in which order to fully understand how to work with typography in ConTexT? (Obviously I am not a typographer or typesetter, I just write documents.) I am in a hurry now to complete my document so I would appreciate concrete hints to help with my current need. Still, I am interested to learn a lot about this functionality in the long term.
