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.

Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
