I'm looking at Zapfino in Font Book and there are a bunch of decorative characters that I want to try out in a design I'm working on (Photoshop 7). If you're on OS X you can see what I'm talking about by selecting View -> Repertoire and scrolling to the very end of the Zapfino page.
But Key Caps doesn't seem to show the characters, the Character Palette won't let you view only one font, and font book won't let you copy a character.
