Developer’s Description
By Nrlz
Extend the functionality of keyword-searches so that they can be activated with the mouse. Simply select some text in your current window and then click on a keyword-enabled bookmark. A search will be performed with the text selection. If no text is selected, it will open the bookmark like a normal bookmark.
This also works inside Web forms. If you are typing some text inside a text box, you can select some text and click on a keyword-enabled bookmark to search that text. This version is the first release on CNET Download.com.
