trouble with dash dance

[IDK]

i'm having a little trouble with some dash techniques. i can fox trot with marth, diddy, lucas, and snake (this ones useless though...) but dash dance... i can only do with my right hand. anyone have any tips? also another question about snake dashing (mortarsliding). i can do it consistently with snake but i was wondering who else actually gets extra slide from it.

do you mean the fox trot cancel dash dance or just dash dancing? for just regular dash dancing quickly (very quickly) move your left thumb back and forth, that simple.
