Instead of sifting through your history looking for that last tab you just accidentally closed, there is an easy key combination that will open up the last tab you closed. Perfect for those few times you are in a rush and you accidentally close something important.
Just hit Ctrl + Shift + T to get it back again. This Function goes hand in hand with Ctrl + T which opens a new tab for you to use at your disposal. Being able to quickly open up a tab I closed has become a useful feature that I use more and more each day. I hope it helps you out!
