To set it up, type: chrome://settings/searchEngines in your address bar. Find where it says "Add a new Search Engine" and fill in the site’s name, the keyword, and the URL.
After you add your bookmarks, just type a site's keyword in the address bar and press enter. Voilà! You are taken right to the site. I prefer to use the shortcut CTRL+L to go right to the address bar, but opening a new tab or clicking it directly work well too.Here is how I have my sites set up, to give you an idea of what it looks like.
Hope this tip helps you!
