What is Double Clutching?
Double-clutching is usually reserved for those driving trucks or high performance racing cars, but anyone with a manual transmission can perform this simple feat. First the clutch is depressed, then the shifter is thrown into the next gear, and finally the clutch is released putting the car back into gear. The driver then depresses the clutch again and completes the shift into the target gear, and finally the clutch is released again, putting the car back into gear. Some large trucks on the other hand have so many gears that synchronizers are inefficient, while race cars can squeeze out more power without them, making double clutching a fact of life. In this case, double clutching by pausing in neutral and giving the engine a little gas to match speeds of the engine and gearbox, can allow such a drastic shift.

Heel-toe shifting technique
My attempt at demonstrating heel-toe downshifting technique. This is a single-clutch technique. Double-clutching can also be useful. Some day I’ll get around to making a video demonstrating that.
