The biggest life changing function in Windows. Used to close Chrome in Computer Science classes. It is also used in online classes to mute the volume of teacher. Thanks Microsoft for this stuff

My teacher asked me to volume down and I told him to press Alt+F4. I escaped from an online class

Alt+F4 

The (not so) secret key combo that every teen must know. Pressing Alt+F4 on an active window closes that window instantly, which is useful especially if you're on something you're not supposed to be on. It works on Windows and Linux, however on Mac, you must instead press command + Q, and if you use a Chromebook, the closest you will get to alt+f4 is Ctrl + Shift + Q, which logs you out if pressed two times.

Seriously, Alt+f4 can be a life saver, especially at class or if you have overprotective/strict parents that makes your house look like North Korea
