Keyboards!

I.... how the frick-frack do you do this- Keyboards! I absolutly love them- But how tuh phuk they work? Like, I understand that they're black and the words appear on the screen because of a little squish thingy beneath the board sends the bianary 1 oh 0 mofo's to the screen but h o w? How do they put the keys in place so perfectly. As I type, my "Y" key is giving me a hard time by poping out of place every once and a while and it sucks.

I think- think how this works in based off of maybe like- little... peices of plastice that they put on the circut board and then the keys snap on. That seems logical, right? I'm not entierly stupid?
