If you've ever wished for the ability to go to the next unread message in Mail, instead of having to shuffle through all the unread ones, some enterprising AppleScript.net forum members have put together a script that might go well with your favorite app/script launcher, such as FastScripts.
I tried this out with my preferred everything-launcher, Quicksilver, and it worked like a charm. I saved the script in Script Editor, then simply added it as a Trigger in Quicksilver with a keyboard shortcut. This has the fortunate side effect of being accessible from anywhere in the OS, so when I press my hotkey, Mail comes to the front and moves to the next unread message in the selected mailbox. Here's hoping Apple's Mail engineering team is listening and has something a little more integrated cooked up for Leopard's Mail.
