When you select text in nearly any program in macOS and then right-click, a Search With Google option appears. Select it, and Safari comes frontmost with the results of that Google search. But what if you want other options?

You should be able to change this in Safari: Safari > Preferences > Search and select one of the four search engines listed there, which includes DuckDuckGo. That doesn’t appear to be working for Forrest, so the following may help.
