Extend the Start Menu Search functionality with Start++

Brandon Paddock (Brandon Live), who works on Search technology for Windows at Microsoft, developed a very useful add-on to Vista’s Start Menu Search box: Start++, it extends the Start Menu Search box, the Run box and the command-line with customizable commands, you can set these commands to run with administrator privileges (sudo command). You can create an alias for anything you want and export it so you can share it with other users.

Type playartist Nightwish and it performs a search for music with the artist Nightwish, writes the results to a .M3U file and play it in Windows Media Player. Type g hullabaloo to search for hullabaloo on Google.
Picture Gadget ^^: Type pic into the Start Menu Search box followed by your query terms.
