How do I do that? There doesn't seem to be any instructions on how to actually accomplish this thing iTunes Help is claiming I can do, namely to be able to change the main iTunes volume (through any of several methods) and have that not affect the speakers I have hooked up through my Airport Express.
I'm well aware I can do this by switching to iTunes, clicking on the Zoom button if I've got iTunes minimized, clicking on the little "speaker" icon (though how that looks like a speaker I'm not sure), choosing "multiple speakers," and dragging the "Computer" slider. OR, if I can figure out how to make iTunes do what the help linked above claims I can, I can just use my Synergy hotkeys to change the volume with a tap on my keyboard.
