Why… do you need to go through DDG for this? You can just set those custom search engines yourself in the browser without routing through DDG. They let you put any link (with %s in place of the query’s location in the URL) and almost any keybinding. I have w set to attempt to pull up the direct Wikipedia article on the query, c for Google Contacts, m for Google Maps (ugh, I’ve gotta figure out a way outta these Google snares…), etc.
