ClipboardTranslator is a free application which allows you to quickly translate any text using Google Translation API without constantly opening the Google Translation webpage. You can also use the application as a simple dictionary.
Of course the translation is not always perfect, so do not rely on it.
Clipboard — listens to the clipboard's content change notifications and translates the new clipboard's text content.
Text — translates text entered by the user.
Each translation is logged, and can be reviewed later by clicking Log button. Translation can be copied to the clipboard using system-wide hotkey (Win+C by default).
