I'm having difficulty accessing font ornaments from ConTeXt. I'm using mkiv. I have a font and I know it has fancy ornaments in it because I see them in the spec sheet. I don't understand what to do beyond this point to find them in the font or get them into the document, and I'd like to know what to do to discover what ornaments there are in the font.
For instance, I know Arno has several leaf-style glyphs intended for decoration. Minion has several heart-shaped bullets. Knowing just these facts, I don't see what to do to get the glyph onto the page.
