SSB4 dashdancing: Inputting a dash in the opposite direction in the first few frames of a dash. In SSB4, any dash inputted this way has no initial momentum, allowing you to make your dash however short you want by timing your release of the stick. If you let go of the stick after only a couple frames, you do a stationary dash. If you let go of the stick after only one frame, you do a Perfect Pivot.

Perfect Pivot: In the first few frames of a dash, inputting the opposite direction for only one frame (can be done by flicking the stick) will perform a regular, lagless standing turnaround animation that can be instantly cancelled with any move. You keep some momentum from the direction of the initial dash.

Fox Trot: Inputting a second dash in the same direction during a specific window towards the end of the initial dash animation. Combined with a perfect pivot, you can do anything out of a fox trot.

Turnaround tilt: Inputting a forward tilt during the run turnaround animation.

These techniques apply to every character, but because Little Mac has by far the best fox trot and FTilt, this is particularly noteworthy for him. Essentially, the combination of fox trotting, Brawl dashdancing and turnaround tilts give him ground options on par with Melee dashdancing and wavedashing.Applications, starring Little Mac (the last two are particularly noteworthy):Foxtrot + Brawl dashdancing:Extended dashdancing:Input: →, →←, ←→, →←, ...Because it gives you no initial momentum, the dashdance length can be reduced to nil with fast enough fingers/a GC controller.Perfect Pivot:Input: →[single frame ←]Fox Trot -> Pivot JabInput: →, →[single frame←]Retreating FTilt (Fox trot, -> Dashdance -> Turnaround tilt):Input: →, →← [wait for the dashdance window to end], →AYou can adjust the sliding distance with how long you hold left.Foxtrot->FSmash (not pictured because this isn't new, but you'll do it a lot when trying the next one so I might as well point out there's an easier way)Input: →, →A"Dash-Canceled" FTilt (Foxtrot -> Dashdance -> Perfect Pivot -> FTilt):Input: →, →[single frame←] [soft→] AThis is hard. You need to both do the input fast enough to do a perfect pivot, without hitting the stick so hard that you perform a FSmash. Possibly a good reason to wait for the Wii U version to play Little Mac, as I feel like this move will murder your opponents and your 3DS alike.
