Simple highlight some text then right click it. You will be presented with a context menu option to search for "highlighted text" on, say, The Pirate Bay. It should be directly under the "search for ... Google" option.
I find a lot of the new content out there by using sites like Rlslog and others "scene release" sites and because of the recent shutdowns/stopping of file sharing for major sites like Filesonic, I'm back to being more dependent on torrents. I love how quickly I can find the absolute perfect match for the file I'm looking for using this. It's a must have.
