I think this should be kIsMuted, right? It doesn't say whether or not the user
pressed the mute key it says whether or not the volume level is currently muted,
which is not the same thing.

"Key" doesn't means a button on Keyboard but an index of dictionary (associative
array). This constant is used as the index of dictionary to pass information
about the volume to Javascript side.

nit: volume should come before window.

Done.
