keybinds to raise/lower volume?

As suggested in this thread, I'm posting a request for the devs: I'd like to see a keybindable command to raise/lower sound fx volume. This would help for glowie hunts, and to adjust volume generally with ease, so it blends right with Skype/music/what have you.

If it's not too much trouble...

/bind keyname "optionset optionname optionvalue"

Unfortunately, I don't know the optionname for Sound FX Volume or Music Volume. But maybe someone can fill that in.

Someone in the other thread checked and optionlist doesn't list a value for at least Sound FX volume.

We've been saving Paragon City for eight and a half years. It's time to do it one more time.

I have a volume button on my keyboard...

I can raise/lower the volume on my headphones, but it doesn't change how loud the game is in respect to Ventrilo, as I usually can't hear my friend if I'm in-combat.
