Help with simple Java Bookmarklet

[Oceanwave]

Please help me with this Google Site Search Bookmarklet. I'd like to remove the function of searching for highlighted text. The idea is to use this in the FF awesomebar with a bookmark keyword, e.g. "s" then the search term. So in the awesomebar you'd type "s search words" and it'd search the current site.

javascript:q=""+(window.getSelection?window.getSelection():document.getSelection?document.getSelection():document.selection.createRange().text);if(!q)q=prompt("Search%20terms%20[leave%20selection%20and%20box%20blank%20to%20list%20all%20pages]%20...").replace(/\s\+/g,"%252B");if(q!=null)location="http://www.google.com/search?q="+q.replace(/\s+/g,"+")+"+site:"+location.hostname;void(0);

Thanks for any help!
