Translation Service for Mac

Translation Service allows you to replace the selected text with a translation in any of several languages—in just one click. It works in any Mac OS X program, so you don't have to copy and paste text back and forth. Services work in applications that were designed for Mac OS X ("Cocoa" applications), such as TextEdit, Mail, Stickies, OmniWeb, Safari, Keynote, and Xcode.

Services do not work in most applications that were ported from Mac OS 9 ("Carbon" applications), such as Microsoft Office, AppleWorks, or America Online. However, services do work in some updated Carbon applications, most notably BBEdit and the Finder.

Further, the selected text must be editable, since Translation Service replaces the selected text with a translation. For example, you can't translate the text in a web page, an incoming mail message, or a PDF. In these cases, you should copy the text to a compatible program, or use the translation window. To translate an incoming message in Mail, just hit reply and translate the quoted message.
