This week's mac techmail is Advanced tips for using LaunchBar shortcuts with Mac. I love LaunchBar and have talked about it before. I absolutely could not imagine life without it, and I'm still learning new things to do with it, so this tip mentions some of that stuff. Specifically, on how to use it to preview music and files, take selections from the Finder and do something with them (like attach to a mail message), and how to input calendar appointments.
