Part od PowerBar, a desktop launcher for the Apple Macintosh. With PowerBar Pro, you can create any number of “toolbars” into which you can drag icons of your favorite or most frequently used applications, files, folders or other items. This extension enhances the 'hot key' feature ( in the Preferences Dialog) of PowerBar Pro, making it work faster. If you don't use this feature, you can erase the PowerBar Pro Key file.
