I have just been using this excellent program called Quicksilver: you can find it in the address below:

This is a utility for us, Software geeks, that we like to type.

Quicksilver is a unified, extensible interface that lets you easily execute commands and manipulate data across almost every application on your computer.

Using Quicksilver, you can open applications, create an iCal event, play a song on iTunes, or email information from your Address Book to a friend.

You do all this by typing quick commands. Let me tell you this is AWESOME. It can really accelerate your work.

Below is the tutorials section:

Please check them out, they will blow your mind.
