The key is used by the layer, not the animation. Animations are just generic
"generators" that take a time value and create a value - it's up to the layer
to decide what to do with that value.
You can always use CALayer's animationForKey: to find out if it the animation
for a specific key:
if ([theLayer animationForKey:@"fadeIn"] == theAnimation) {
}
