I added a search engine to the list of search engines.
How did I do that? I went to the website. I long-tapped on the search box. In the window that appears at the bottom, I chose "Add search engine...". That search engine now appears below the list prepopulated with Google, Yahoo, Bing, DuckDuckGo, Amazon, eBay, iMdb, Wikipedia.
How do I remove the search engine I've just added?
I can't find a way to do it in the Settings.
