Clear All Growl Notifications
When IM errors occur, I have Adium’s Growl alerts set to remain onscreen until I dismiss them. Unfortunately, sometimes I accidentally leave Adium online when I go to work. When I get back home, I have a huge number of notifications waiting to tell me that my user for service X is logged in from multiple locations.
As it turns out, there’s a simple way to close all notifications at once—just hold the Option key before clicking on the first notification.
Take that AOLSystemMessage guy.
