Update the default list of search engines in Chrome
Chrome allows you to manage the list of searches available via the address bar. You can add new site searches and such by clicking the Add button. What you can't do is move a search engine from the "Site search" section to the "Search engines" section. You are effectively stuck with the list that Google curated. Here's how to fix that.
Side note: The data we want to edit is stored in a SQLite database. You'll need a copy of the SQLite command line tool for your OS in order to edit this database. Good news, SQLite is free software! Just run on over to the SQLite home page at https://sqlite.org and hit the download button.
In your browser go to chrome://settings/searchEngines
