Browsers: Edge: losing tabs, then getting them back

Self-tutoring about the Edge browser: the tutor mentions losing tabs.

I like to leave tabs open when I expect to return to them. This morning, I went to Edge, but all my tabs were closed – only the greeting tab remained.

I looked around a bit on the Internet for an idea about what happened. Next I checked the history of the Edge browser. It listed all those tabs, but didn’t say they were recently closed. Where did they go? I wondered.

Out of curiosity, I pressed Ctrl+Shift+t. All of the lost tabs (around 30) returned.

Interesting, eh?
