One of the most important feature of Artha that makes it handy is the hotkey lookup feature. When you are reading an article in the browser, or composing a mail on a mail client, or working on the Terminal, be it any window, when you select some text in it and press the pre-set hot key combination assigned to Artha, it will pop-up with the definitions of the selection made of that window.

When Artha is run the first time, after installation, it will try to set an arbitrary hotkey, in the order:
1. Ctrl + Alt + W
2. Ctrl + Alt + A
3. Ctrl + Alt + T
4. Ctrl + Alt + Q

When one fails it tries to set the next. If all the above hot keys are pre-occupied by some other application, no hotkey will be set. You can change the same via tha hotkey editor to whichever key combination you prefer.
