My wave or the Shortwave?
Shortwave is an extensible quick-search and shortcut system.
Shortwave is a quick little app that Shaun Inman created in 24 hours (a current trend, I’ve got one coming soon too!) that is proving to be a very useful little tool, especially on the iPhone. You can customise the shortcut system with your own commands, my waves.txt file includes a few additional commands including Google UK Search.
