As a heavily-reliant Quicksilver user on my MacBook Pro, I was glad when I found the Teleport module for Drupal (due to Elliott Rothman's tweet).
When you press a configurable hot-key, a jQuery dialog box appears where you can search for nodes by title or path, or directly enter the path that you want to navigate to. This will greatly reduce the number of clicks that I need to perform to get to my desired page - even compared to the Admin and Administration Menu modules.
Although it's not a new module (the first commits were 2 years ago), I hope that they are still planning on achieving the list of future directions listed on their Drupal.org project page:
Personally, this will make navigation around both the front-end and administration area of my Drupal sites so much easier, and is a definite contender if I decide to do another 10 Useful Drupal Modules list...!
