Ergonis has released KeyCue 6.3, which adds compatibility with OS X 10.8 Mountain Lion to the keyboard shortcut utility and ensures that KeyCue’s new technique for adding the app to the Login Items list now works with the big cat. The update also fixes an issue that caused group titles to appear white on white while editing custom shortcuts, improves the Start at Login setting when KeyCue has been renamed, and plays the Installer’s completion sound through the “sound effects” channel while respecting the volume level set in System Preferences. (€19.99 new with a 25-percent discount for TidBITS members, free update, 2.2 MB, release notes)

In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
