Shortcut to access Sound Preferences on Mac OS X

Sound

When you click on the sound icon that is docked at right corner of the menu bar, it displays a slider for you to adjust the volume. To access the advanced sound preference, you can Option-click on the same icon to reveal a menu that allows you quick adjustment of the input and output devices, and also access the Sound Preferences.

The Sound Preferences can off course be accessed via the normal System Preferences->Sound. A keyboard shortcut to get to the same Sound Preferences is to hold the Option key while pressing the Volume Up, Volume Down or Mute button on the keyboard.
