It does nothing.

I gave you 5 stars because there is no other application in this moment. But like I told you on the e-mail which I sent to you. It will be far better if you use the shortcut directly , without "u" prefix. "google" instead "u google"...
Cheers!
Edit: I edited my review to 1 star because the developer it seem to not care about our opinions... Not even one small answer with any word
