OS X users can now search Google with their selected text, thanks to the SearchGoogle service, from Jak Dorsey at gu.st~* LIFTworks!. From the Web site:
A simple background service to allow you to select text in (nearly) any application and press "Shift-Apple-G" to launch a Google search for that text. This release is context aware. When you select text from Project Builder, a browser opens up searching developer.apple.com instead of Google. You can define your own contexts (application-grain) and choose what URLs they apply to.
SearchGoogle can also be modified to search other websites, and is public domain software, although a donation or a postcard is suggested. Both the source and the service file may be downloaded from the gu.st~* LIFTworks! Web site.
A link to this was originally at the Power Page, and we thought it way too cool not to mention again. Itis also important to note that Services are only supported in Cocoa applications, and the Carbon apps that have been coded to support it.
