Rev matching what?

you control the stick but the car adjusts the rpm so that your next gear is engaged smoothly.
Imaging driving at 2000 rpm in 5th, you want to down shift but keep your speed constant so the new rpm is 4th gear would be 3000 (just for this explanation). if you move from 5 to 4 and engage the clutch the car will jerk. By rev matching you bring the engine to 3000rpm before releasing the clutch and the gear is engaged smoothly.
This makes for a comfortable ride on the street and doesnt upset the balance of the car if you change gears mid turn
Before this feature you would "heel toe" by pressing the brake with your toes and use your heel to work the gas
you can see at :30 bellow

I read that the tabs on the wheel just turn on and off rev match, and the sensor in the gear lever can tell if you are up shifting or down shifting and can even tell if you are going from 1-4th or skipping gears. But I do find it odd; why two switches?

I think I understand. When I use to drive a stick, I would need to downshift when I went from something like a 50MPH zone into a 30. If I didn't give it a little gas the car would jerk and the engine rev. It make a smooth transition. So rev matching does it for you.
Other than that, I always put the car into neutral (or push in the clutch) when coming to stop. I don't down shift through the gears to slow down. I always thought engine braking is overkill on a car since its not like a truck that is hauling a couple thousand pounds. Its just nice to hear the power of the engine as you slow down I guess. But I am not a racer, so I can see going really fast and needing the RPMs high.

#1...i have known countless people that claim they heal-toe well, and cant for ****
#2.. Many people who think they are mr badass behond the wheel dont even know what a heal toe even is. I've listened to club road racers downshifting and using only the clutch to bring the engine to speed
#3...despite the fact I heal-toe 100% of the time, street ot track, regardless of what I drive, I still can see this feature being a great addition and option. Unless you heal-toe OFTEN, most people dont apply effective consistent threshold braking while blipping...they lift momentarily. Point is, the system is a great thing, despite corvettes being some of the easiest cars to heal toe I've ever driven.
