• adjust audio volume
• mute audio
• activate screen saver
• disable screen saver

• shutdown computer

For example, instead of double-click on the small yellow speaker icon in the system tray to bring up the Volume Control applet so to adjust the audio volume, you can simply assign two hotkeys, one to turn up and one to turn down the audio volume, just like what you have on your T. V. remote control unit.

Besides, you can also assign a hotkey to toggle the audio mute function.

If you have a CD writer and you don't want the screen saver to ruin your day while burning a CD, you can assign a hotkey to conveniently disable the screen saver instantly. When you are done with the CDs, press the hotkey again and the screen saver comes alive.

Lastly, like the "Power" button on your T. V. remote control unit, you can also assign a hotkey to shutdown your PC.
