However, many of us probably are not aware of the feature that is available in chrome browser to switch to exactly the 3rd or 5th or 7th tab directly using the keyboard.
Simply, by pressing ctrl+1, ctrl+2, ctrl+3 and so on you can directly go to the 1st, 2nd, 3rd and their following tabs respectively. Just by pressing ctrl+4 you can directly go to the 4th tab of your chrome browser.
But there is a limitation of this system, there is no way to go to tenth tab and onward, since there is no key with the numeric 10, 11, 12 etc. Nevertheless, when you have more than 9 tabs opened the ctrl+9 function will take you to the last opened tab, may the the 11th or 19th or something like that, depending on the what is the number of the last tab that is open. In such cases, ctrl+8 is the last key that follows the numeric order of the keys 1 to 8 and then it directly shows the last opened tab by pressing ctrl+9.
I found this feature to be present in the chrome browser of my Chromebook although not yet tested in other kinds of operating systems or browser. Probably, the feature will be present in other any chrome browsers.
