How nice it is to just stay on the terminal with hands on the keyboard, staying away from that wierd mouse. I just configured centericq for that particular purpose. Its pretty simple.
Step 1. Install the centericq package :
$ sudo apt-get install centericq
Step 2. Configure it for the Google Talk:
Server : talk.google.com:5223
Secured : yes
Login : ********@gmail.com
Password : ********
Priority : 4
Update user details
Set away message
Step 3. What are you waiting for now? Just chat!
