L-canceling

L-canceling (an abbreviation of lag canceling and also known as smooth landing) is a technique in Super Smash Bros., Super Smash Bros. Melee that shortens the ending lag when hitting the ground during an aerial attack. Only regular aerial attacks can be L-canceled; special moves that have landing lag cannot.

In Super Smash Flash 2; landing lag is intentionally timed to resemble the length of an L-Canceled landing animation, which is referred to as 'Auto L-Cancelling' or 'Aerial Lag Reduction'. This allows for both new and experienced players to perform combos without needing to press the shield button as they land.
