AuctionMac software has released VolumeKnob 1.01. VolumeKnob allows the Mac's system volume to be controlled via keyboard commands, rather than having to go to the systems sound volume controls. Keyboard based sound controls are common on many laptops, and having similar desktop functionality could prove useful. According to AuctionMac:
AuctionMac Software is proud to release VolumeKnob v1.01! VolumeKnob is a Macintosh utility that allows you to easily raise and lower your system sound volume directly from the keyboard. With powerful options and more precise settings, VolumeKnob will replace your volume control strip. VolumeKnob is perfect for music lovers, headphone users, sound masters, MP3 users, or anyone that frequently needs to change their system volume quickly and precisely.

Set system volume directly from the keyboard from within any application!
