All utilities from the F1 to F12 key

The F1, F2…F12 keys are quite mysterious. We have them in front of us whenever we use a keyboard, but we rarely use them much more than to refresh the screen with F5, and if we are a bit of a saucer, we can even use F2 or F8 to access the computer’s BIOS and perform some changes in system configuration.

We see these keys constantly, but could you tell me what the F3 key is really for? Did you know that in some programs, if we press F10, the program shows us all the keyboard shortcuts graphically?
