Alternative Ways to Control The Volume Level Of My Mac In OS X? Generally to either increase or decrease the volume level of my Mac, I always go to the volume menu bar and adjust the slider accordingly.

I was wondering:

What other ways exist within OS X to adjust volume settings and perhaps give even finer adjustments to the volume level that is produced ?
Use the volume keys on your keyboard (hold Shift + Option for finer control)
Go to the Sound pane of System Preferences
