moving unlimited

i'm trying to make a cinderella game, where she can move. right now if you press the up button, she moves 1 meter. how do I get her to move forward until the up button is released (like in most video games?)

i just figured it out, but i don't want cinderella to move quite so fast. how can you make her go slowere so she doesn't keep zooming off of the screen? also is there any way to make the camera follow cinderella?
