You probably had no idea what the F10 key does in google chrome unless you accidentally bumped into it, and then you will never forget. amirite?

Epic fail 🙈

What's it do?

Alt+F4 has always been the most useful though.

The good ones are F6 and F12 as well. Just try them.

wondering what would happen if all the keys were pressed at the same time

I just tried them all, only nothing happened except image below, hope you can see it..
