If you perform a melee attack while strafing, it is like a hidden quick dodge move. It is useful for dodging sentinel fire. If you perform a melee attack while moving forward, you gain a quick forward dash for a second. Melee while moving forward and while standing still in the middle of the melee animation do a quick jump to perform a quick bunnyhop dash forward. Maintain your height with the jetpack to cover a very long distance quickly. You have to quickly jump after melee to get this to work (at least within a quarter second of pressing [Melee]). This can also be applied in strafing directions as well.
