Tip: Silence that annoying beep
Here's a tip that some of you may not be aware of. Don't you just hate the annoying beeping sound your Mac produces each time you use the volume keys on your keyboard? I sure do. You can silently raise or lower the sound by simply holding down the shift key while pushing the volume keys. Unfortunately, this trick won't work with the volume slider in the menu bar, so stay away.
