This is a very simple little tip of which most people are already aware, but here it is anyway.
Google Chrome does its best to identify situations when you’ve highlighted something it can interpret as a URL, and gives you the chance to navigate to that location in a new browser tab.
For example, when you receive an email containing an email address, you might sometimes want to visit the website hosted at that address’s domain. Take a look at the example in the image; in this case, I want to visit the Brittany Ferries website:
I can save myself a little typing (or cut-and-pasting) by simply highlighting the domain part of the email address and right-clicking on it:
The pop-up menu has an option to visit the highlighted domain, with the page opening in a new tab. Chrome will offer this service provided the highlighted text is something that looks like it can be interpreted as a valid URL.
