 You can add more search-engines by copying the line below, 
 pasting it under the allready existing lines, and editing it:
 
 engines['QUICKNAME'] = "NAME; URL";
 
 You have to split the NAME and the URL by using '; '.
 In the URL you can use %KEYWORDS% instead of the keys searched for. As you see below.

engines['live']  = "Windows Live; http://search.live.com/results.aspx?q=%KEYWORDS%";
engines['yahoo'] = "Yahoo!; http://search.yahoo.com/search?p=%KEYWORDS%";

engines['ytube'] = "YouTube; http://www.youtube.com/results?search_query=%KEYWORDS%";
