Opera and Opera GX have their own default key bindings for different browsers (w for wikipedia, d fof duck). Not only is it impossible to turn it off or change it, the only roundabout way was blocked by the developers (changing some files). I heard it's a "requested feature" but well, it's been a few years already and devs don't seem to give a ****. Files' names suggest that those sites are Opera's partners. I don't care if they are their partners nor parents, it pisses me off when I can't start searching from "w ".
