Smash Ace
What to do: Press ->B and jump within a few frames of each other.
What happens: You jump rather high (higher than short hop, shorter than a full jump) and you do it Quickly. You jump much faster and higher than when just pushing jump and then ->B.
Depending on the timing, you'll jump higher or lower.
Practical applications:
1) you can dash, and instantly backwards cape at a higher height than trying to quickly push Y/X ->B.
2) you can approach, capejump, make the opponent whiff their attack, and buffer a fair which has just enough time to get the hitbox out. At certain percents, you might be able to combo it into a usmash if they don't tech the ground.
Also, the best way to try this is to use R or L to jump, and go R->B. I doubt it's possible any other way.
