Here another script for bookmarklets that can be very useful: just select an address, or the name of a city or country in a webpage and click on the bookmarklet. In a new tab you will have the result of the selected text in google maps! Very time-saving if you need to organize your holidays!
Enjoy and leave a comment plz!
