This is my favorite Windows keyboard shortcut. In most web browsers, if you press Control-Shift-T, the previously closed tab will reopen.

So, if you closed a browser tab by accident, this shortcut undoes the mistake.

Even better: if you press this key-combo multiple times, your browser may be able to reopen many of the tabs you’ve recently closed. If your browser has been open for a long time, this may be able to reopen something you used many hours and tabs ago!

Sure, you can go through your browser’s history to relocate things you’ve closed, but this shortcut can save so much time. If you work in multiple browser tabs all day long, practice and use this one, I bet you’ll appreciate it at some point.

Oh, and it’s Command-Shift-T for Mac users!
