But in versions of OS X prior to 10.7, it was possible to adjust the volume in smaller increments: If you held down Shift and Option before pressing the Volume keys on your keyboard, you could adjust the volume in quarter-steps instead of whole ones.

In addition to using this Shift-Option combination to control the volume more finely, you can also use it when you adjust the brightness on your Mac. Press Shift-Option, then press one of the brightness keys on a Mac keyboard, and you’ll notice that the brightness changes in quarter-steps. This is nice if you find your display is just a bit too bright or too dim.
