Chrome has a hotkey to re-open closed tabs. That's right. Ever close a tab and wish you hadn't? I sure have. Ctrl+shift+T, my friend. Oops, you closed 3/5 tabs and you wanted all of them open?! No sweat! Just hold ctrl+shift and tap T 3 times... No worries!
Seriously, this is a powerful little trick that might save your ass some day.
And you thought that tab was history...
