What's the best way to browse keystrokes for ornament fonts?

I have a number of fonts that are non-alphabet ornaments, such as Monotype Rococo and Adobe Woodtype. I can look at a selection of the ornaments in Font Book, of course, but if I see an ornament I like, I have to guess which key to hit to get it. If it's the first ornament in the top row, of course I know I use capital A, but God help me if it's someplace in the middle of the fourth row. The obvious solution -- opening Keyboard Viewer and choosing the ornament font as the displayed typeface on the keys -- is unavailable due to some technical limitation of the later OS's that I don't understand.

Character Palette sort of works, but very clunkily. Basically, I pull up the latin alphabet, then go down to choose the ornament font in the Collections window below and then click letter by letter above. I do see the ornament each key gives me. But I'm seeing them one at a time and am giving up the at-a-glance scan of the available ornaments I'd have just by looking at a keyboard.

If anyone has a better way of browsing keystrokes for this kind of font, I'm very, very interested!

Thanks.
