...and would like to have a very small, easy to use application that can be launched by a click of your mouse, then seriously, Translate Me is pretty awesome. It supports a lot of languages + you can use more than one "Translate me" windows at the same time by using your keyboard (Control + Enter, for switching between many) as well.
|Ohh, now I understand your language pal :)...|
The developer has added few new features to this latest version which is now 0.3.9.4 such as text deleting button, etc. If you use Ubuntu 11.04 Natty Narwhal, then you can install Translate my by issuing the below command.
sudo add-apt-repository ppa:atareao/atareao
sudo apt-get update
sudo apt-get install translate-me
