It’s all too easy to accidentally close a tab when you’re browsing the web. Especially frustrating if you’re reading something interesting, such as the EJC website. Just press Ctrl + Shift + T and the last place you were looking will magically reappear. On a Mac it’s Shift + Command + T.
This works in all the main browsers – Firefox, Chrome, Microsoft Edge, Safari. You should also be able to right-click on the tabs at the top of your browser and there will be an option to ‘Undo Closed Tab’.
