Did you know you can undo a sent e-mail in Gmail? It’s a lesser known feature, but Google just made it even better than it was before. When it first launched, you were given a 5-second window during which you could hit “undo.”

The feature is hidden from most users who don’t know where to look, so here’s a quick guide to avoiding social and workplace faux pas with the click of a button. Be aware that the feature is part of Gmail Labs, though. That means it’s still in testing and it might not always work as intended.
