I want a
dictionary or translator that uses or near to Google translation for translating from English to Arabic, vise-versa or between any languages, so What is the best
it would be better if this program has an indicator or launcher quick-list???
I usually use "Gnome Translate" for this. It's based on libtranslate, which can use several on-line services (including Google Translate, SYSTRAN, etc.) to translate text. There is also a commandline version:
This one may do the job:
The HotKey is Ctrl+Alt+W. You can just select a word in any software and press the Hotkey combination to invoke Artha, its notification/window will then come up with the meaning
Google Translate Desktop
You can install Google Translate Desktop, it's written in Java and because of that runs everywhere, it also uses the Google Translator API.
