On Mac OS X 10.8.2, shift-clicking the volume control menu extra causes a slider to come up. This slider's value is persistent, but different from the usual volume control's value.

What does this other slider control?


The shift click slider controls the volume for Alerts. You can check for yourself in the Sound preference pane.
