How does the Audi R8's synchro-mesh transmission work?

I heard that the Audi R8 has a unique synchro-mesh transmission, but I'm not sure how it operates. Can anyone explain the mechanics behind it?

The Audi R8's synchro-mesh transmission uses a synchronizer unit to achieve smooth gear shifting. As the gears are engaged, the synchronizer unit temporarily locks the gear to the gear shaft, matching their speeds before the actual engagement. The result is a seamless and efficient gear shifting process.

One of the main advantages of the Audi R8's synchro-mesh transmission is its relatively low weight, making it more efficient and responsive than other types of transmissions. Additionally, the synchro-mesh design allows for closer gear ratios and smoother gear shifts at high speeds.
