I'm not too sure if this has been brought up, I tried searching the forum for it but nothing came up, I haven't had a lot of time to post lately, but it's summer now so there's lots of time. If it's already well known, my apologies. Anyways, a little over a month ago I saw a post on the Zelda forums where if you did a ledge jump you can cancel the jump as soon as you leave the ledge with any of her b moves.
So naturally I tried it out with Yoshi, and was actually able to do an egg roll from the ledge (very similar to the one from melee). The timing is a little tight, but all you do is tap the jump button when you're hanging on the ledge. As soon as you leave the ledge, you do an egg roll away from the stage, then you slam control stick back towards the stage so that you have the egg roll going at full speed.
