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.

\getnamedglyphdirect{FontName}{GlyphName}and\getnamedglyphdirect{FontName}{char_no}don't use square brackets? It seems inconsistent with usual Context conventions. – Charles Stewart Feb 18 '13 at 19:56\in{section}[sec:foobar]. Though, many internal commands use braces because those macros are simpler to write (\def\foo#1#2#3{…}) and a little faster. Furthermore, braced arguments are more robust since they can be nested. Regarding this example if\getnamedglyphdirectwould have used brackets for the font name, additional braces would be necessary since otherwise they would interfere with the brackets from\definesymbol. And, last but not least, sometimes it's just inconsistent and there's no real reason. – Marco Feb 18 '13 at 20:21\getglyph). – Charles Stewart Feb 19 '13 at 10:46
