While in the air, you can fire a CS in the other direction. If your facing left, tap right and then quickly press B. If done too slowly you fire to the left. To quickly-- you were still pressing right when you pressed B -- and you end up firing a missile to your right.
You can turn and quickly fire CS on the ground as well. During an attack, in the last few frames tap in the opposite direction then press B. Samus will immediately turn and fire her CS after finishing her attack animation. This is mostly easily done with the jab attack. A surprise combo is Samus's dash attack that hits the opponent w/ low percentages and you end up behind them... you then turn quickly and CS.
Another application is stopping a run with a shield. By tapping shield during a run, samus will flash her shield. When her shield flashes off, she's stuck in a brief animation before you can move or attack. During this animation tap in the opposite direction and then press B (tapping in the opposite direction too soon results in a rolling dodge). In this way, you can sprint past an opponent and then quickly turn and fire (another is short hop to CS pivot).
This is similar in some ways, but different then the technique in this vid where falco turns in the opposite direction during the first initial frames of drawing his pistol:
