Quicksilver is probably the most difficult of the Top 5 to explain mostly because it just does so many different things. First and foremost it's by far the quickest way to launch applications. Instead of having to navigate through finder, applications and then find your application, you type a quick hot key (of your choice) and begin to type the name of the app. A window appears with the list of applications as you type. Once you've found the one you're looking for, you press enter and the app launches. There are also tons of other plug-ins that give you the power to do all kinds of things right within the Quicksilver window. Things like, create and manage contacts, create an iCal event, send an email, search the web, play a song on iTunes, and on and on. With all that said, let me show you how to set it up and use it!
Once Quicksilver has been remotely installed on your computer, it will be in your applications folder. The first time you launch it, you'll be taken through the process of setting it up.

You'll be asked if you want to install any additional plug-ins. I chose the iChat and iTunes modules. You can mess around with any of these.

The next window is where you can set your hot-key. Click on the Hot Key space and type whatever you like. I'm going to use Option-Space bar.

Once you're done setting it up, you're ready to rock. All you have to do is press the Hot-Key you chose and this window will appear: (it may look different depending on your settings)

Begin to type the name of any application and Quicksilver will search and display the results as you type.

Once you've got the one you're after, press enter and the application will launch! One really cool thing about Quicksilver is that the more you use it, the more it learns the way you work. If there are applications you launch often, it will put them high on the list so you get to them faster. Soon you'll be launching applications faster than you ever thought possible. And don't be afraid to check out all of the other cool features and plug-ins! If you fall in the love with this app and really want to dive into all it has to offer, you can find all kinds information at http://docs.blacktree.com/quicksilver/what_is_quicksilver.
