So, the thing is, you don't have to press a key on your keyboard to type in a letter or number. For example, the letter "a" can be typed by pressing the A button on a qwerty keyboard.
So, how does it work? Well, like I said earlier, you don't need a key. The computer does not use the keypresses of each individual key to write letters and numbers. Instead, they are programmed into the hardware of your keyboard. So when you press a key, that key sends electrical impulses to the processor in your computer which tells it to display whatever was programmed into it (i.e., the letter "a") on your screen.
This makes sense because if you think about it, you would have to press more than 100 keys on your keyboard to type out each word in an entire sentence! And there are lots of other things that we take for granted as well (like typing with one hand).
So, basically what this means is that every time you hit a key on your keyboard, your computer gets the message that you want it to do something based on what was programmed into it, not what key you pressed.
