Comment 7 for bug 725177

This is a question for Ayatana Design and is not an ido / indicator-sound bug -- they are behaving as per the specification. <https://wiki.ubuntu.com/SoundMenu> "Whenever the volume item is highlighted: The Left and Right arrow keys should instantly decrease or increase the volume, respectively, to the nearest 5 percent step. "

And, as the original description says, it would be counter-intuitive to have the volume levels work the other way around.
