Such Pretty Little Things
Shopping around for keyboard parts is a dangerous thing. There is a layout for everyone. A skill level for everyone. Keycaps for any style. Those are all expensive fancy things. You don't neeeeed the keys to be fancy colors or have an aluminum block housing. Lights might be needed if you are an older person who was never taught touch typing, but there is one little thing that really is important to your keyboard... the switch.
That little bit of mechanical actuation that closes the circuit when your brain says “Press the letter A.” (Even if it's a mushy plastic square that Apple keeps insisting is a key.) The switch is what connects you physically to the letters that pop up on your screen. It completes the metal on metal circuit, signaling to a chip that you wish to have the letter A show up on the console, in a word processor, on an email.
Those little guys come in different flavors, colors, shapes, and sounds. Yes, sound is important in typing, just like hearing the crunch when you eat chips that tells you they're fresh. Hearing the THOK TICK or THUNK of your keys as you type tells you you've made contact with those circuits, that you're being productive.
....and sometimes they are $2-4 dollars a pop and you just keep adding them to your cart and closing the browser window because you already have three sets and you don't need these just because they are lime green.
