What is Pause Break key for?


Imagine… It’s around 2:30 p.m. You’re stuck at work, and you’re desperate to get away for a coffee because your boss is breathing down your neck for, I don’t know, a line graph or something. But suddenly, you glance down at your keyboard, and you get an idea. What would happen if I actually hit the Pause Break key?

So you spring into action, mashing your index finger down on it, and as it bottoms out, your boss freezes, and a delightful coffee appears right in front of you.

So a far more common use for you would be to pause that flow of text you might see on own computer at boot time, like if you would like to see BIOS messages that might help you understand or troubleshoot any issues you’re having. Now, it doesn’t work on every PC, but give it a shot the next time you fire up your system if you’re curious.
The Pause button will also stop any huge avalanche of

Holding down the Window key and pressing Pause Break will bring up your system property screen. And some games will let you press Pause to pause your gameplay. Makes sense, right?
It does make me wonder why that isn’t the standard, but even if your favorite game doesn’t use the Pause key for
