When you close a browser tab prematurely, whether it's by accident or, unbeknownst to you, you're going to need it again moments later, it's no fun digging through your history to get it back. That's why Control/Command+Shift+T was invented. It resurrects your fallen tabs from the graveyard of your browser history.Just to be clear, that's Control+Shift+T on Windows and Command+Shift+T on Mac OS X. It doesn't work on every browser (like Safari, which can sort of do it with Command+Z) but it's present in most and infinitely helpful. If you haven't used this great shortcut before, you'll wonder how you've ever managed to live without it.
