Here are a list of some useful keyboard shortcuts for internet web browser tabs

Switch Between The Tabs
The formula is CTRL + n (where n is a Tab number from 1 to 8). For e.g. If you want to open Tab no. 4, then press CTRL + 4.
Even, If you have opened more than 9 Tabs in a browser, than pressing the CTRL + 9 will open the last Tab in the browser.
Note: Since there are only 9 numeric keys on your keyboard, that's why you cannot open Tab no. 10 or 11 and so on using this keyboard shortcut. But you can press CTRL + 8 and then use CTRL + TAB to go to next open Tab.
Re-Open Closed Browser Tab
If you accidently closed any browser tab and want to re-open it, than simply use CTRL + SHIFT + T. (Cool Isn't It)
