His life, if I may make a logical leap, has forever changed. I’d argue that it’s one of the most important and useful keyboard shortcuts there is, right up there with Ctrl+Z. In fact, it performs a similar function: undoing a mistake. Specifically, the mistake of accidentally closing a browser tab or window. Ctrl+Shift+T is the easiest way to restore a browser tab you didn’t mean to X out.”
