Quick site search using Chrome's Omnibox

Before starting the tutorial lets first see what's an Omnibox is?
Omnibox is a prominent feature of Google’s Chrome Browser. Omnibox is Chrome’s combined search and address bar, which allows you to use the address bar as a search bar. All you have to do is to type a search term in the address box (Omnibox) and press enter to see results from your default search engine.

But other than this there is a reaaly cool feature which is hiding in it, lets reveal that.
You can use your address bar to search sites that you've previously visited.

Say you frequently go to YouTube to watch funny videos. The next time you need a good laugh, just start typing "youtube" in the address bar. After a few letters, the address bar will automatically offer you the option to search the site.



Now the cool trick: hit Tab on your keyboard to convert the address bar into a search box for the site.



Then type what you're looking for and press Enter. Google Chrome will immediately bring you to the search results page on that site. In this case, you'll see YouTube's search results page for "dog on skates":



Use this "tab to search" shortcut to save yourself a few clicks the next time you want to quickly search a site.
