Accidentally closed a browser tab? Instead of trawling through the browser history, get a recently closed browser tab back by using the Ctrl+Shift+T shortcut key. This will quickly re-open that tab. Use the shortcut keystroke again and it’ll open the tab you closed before that, and so on. This should work in IE, Firefox and Chrome, indeed it may also work in other browsers – try it.
You can also right-click on another tab and use the ‘Reopen closed tab’ (or similar) option, this is available in all three browsers as well.
