Edge dashing
Edge dashing is basically starting and ending an initial dash at an edge, without falling off. It can be used in a taunt match to show off, but can be used to attack as well.
How to perform
The player should get close to the ledge, and simply tap as fast as the player can towards the ledge. One way to do it is to hit the control stick to the desired direction, while letting the player's finger slides off so the control stick returns to its original position. The player's character will start a dash for one frame without falling off the edge of the platform.
Dash attack
If the player is using a GameCube controller or Classic Controller, they can use the C-stick or Right Control Stick to perform a dash attack next to an edge. As the player hits the left control stick, hit the C-stick in any direction but up. The player doesn't have to let go of the control stick this time, they just have to make sure the C-stick comes right after the left control stick.
If the player tries to use the A button instead of the C-stick, they'll perform a f-smash. If the player is using the C-stick and they perform a d-smash, then they hit the C-stick too soon.
