Drag & Drop Search is a handy extension for Google Chrome that allows you to refine web search tasks through drag and drop actions.
Simply select (hightlight) the desired phrase or word with your mouse, drag and drop it in the search field. You have the choice between several search engines (Google, YouTube, Facebook, Twitter, Yahoo, Bing, MySpace, Wikipedia, etc) arranged in the form of a grid.
The grid is customizable and can be configured with up to 16 search engines. The results are displayed in a tab next to them.
