how to make player move with no gravity

How do I make it so the character can move in air without gravity like in an RPG?

Turn off gravity, have a key connect to a number and connect to x or y of a velocity.
After you have all 4 directions connected to numbers and the velocity, have all the directions (up) connect to the number 0 and connect the 0 to both x and y, so when you let go of a button, you stop instantly.
