You can add custom search engines to Google Chrome, allowing you to quickly access and search specific websites or apps without having to open them first. To do this, you need to follow a few steps, including opening the Settings page, clicking on Search engine and then Manage search engines and site search, adding a new search engine by filling in fields such as name, shortcut, and URL, and finally clicking Add. Once added, you can use your custom search engine by typing your shortcut, pressing Tab or Space, and entering your search term in the address bar. You can also add custom search engines for websites without a search bar by copying the resulting URL from a sample search term followed by the site URL, pasting it into the URL field of the Add search engine pop-up, and replacing the sample search term with %s. Additionally, you can automate your workflows using Zapier's free Chrome extension, which allows you to automate critical tasks with the push of a button in Chrome, eliminating the need for tab-switching.
