Is #duckduckgo your default search engine?

Then, if you use #OpenStreetMap a lot, you might find it interesting thing to know that there are #bangs focused on OSM that you can simply type in your browser's search bar

!osm <something> - search for "something" in OSM.
!osmw <something> - search the OSM wiki (very good results!)
!taginfo <something> check for taginfo data about tagas or key/key-value pair
!otw <something> data mining query with #Overpass

and more!
