How to separate animation data between duplicated armatures...?

I’ve got a working walk cycle using one character. I’d like to simply duplicate both the character mesh and armature and alter the walk slightly for a second character. However, I can’t figure out how to separate the armature’s animation data from each other. e.g. When I alter one’s timing or motion, the other is also affected. I know exactly what I’d be looking for in 2.49 (you just hit the number indicating the total users while in the IPO window) but I can’t find the right menu or button in 2.5… It’s basically the same thing you do when you make a duplicated mesh or object a unique user of any other kind of data: materials, textures, objectdata, etc.

Anyone know where this thing is hiding?

Edit

Just in case anyone else is ever looking for this:
The command is called “Make Single User” and it’s actually in the 3D View window, not in any of the animation windows. In object mode with your armature or object selected (not pose mode) object > make single user > object animation.

I’m glad I found it, just miffed that it wasn’t at all where I was expecting it, lol.
