Tested "Our Favorite Keyboard Shortcuts by Norman Chan By far our favorite keyboard shortcut ever. Used in any modern web browser, Ctrl + Shift + T (in either Windows or OS X) lets you restore your last browser tab that you closed. Yes, you can turn back internet time! In Chrome, this lets you restore up to 10 tabs. We love this shortcut so much, we even made a video about it."
OK so its not actually a video, just a series of photographs, but several of these were pretty obscure so check them out :-)
