Close tabs (and bring them back)

If you want to close down the tab you’re currently looking at, it’s Ctrl/Cmd+W—and if you want to, you can keep going to close down the current window, too. Assuming you haven’t quit Chrome entirely, you can use Ctrl/Cmd+Shift+T to bring back the tab you closed most recently and keep tapping the same keyboard shortcut to bring back older tabs, too.
