Lots of confusing misinformation in this thread right now.
Starting from the Top, Yes there is a high probability a short shifter will reduce the lifespan of a transmission. BUT it is very dependent on how you drive the car. Synchronizers need time to work properly and mesh prior to the main drive gears engagement. By reducing the amount of time the transmission has to make this work the more likely you are to run into issues when changing gears rapidly.
Double Clutching and Heal toe down shifting are completely different from on another.
Double clutching is an old school technique to smoothly shift (up or down) from one gear to the next on older cars with non-synchronized manual transmissions that do not have fancy double and triple mesh synchronizers doing all of the work for them that we are all spoiled with today. Basically you would use the double clutch technique to ensure the transmission has enough momentum to smoothly transition from one gear to the next which is no easy task in a car with a straight cut gear especially if you are driving like a reasonably sane person.
Heel toe down shifting is the act of simultaneously braking and doing a rev matched down shift in one fluid motion without upsetting the balance of the car.
Rev matching is a generic term of matching engine speed with the gear you are down shifting into and it will also alleviate drive train shock and wear.
