Something to think about for future Blender versions: The ability to change the words “Key1”, “Key2”, etc, to meaningful names…

“Was the left eyebrow Key26, 29 or 412???”
You can already do this. Once you have your keys defined, go into the Actions window for your mesh. Your keys all appear here, with an option to show RVK sliders. Hold the mouse pointer over the key name (Key1, Key2, etc.), press N, and you can rename the RVK!

Really? Excellent! Thank you!
-Iain, off to try it…
