Using MouseEvent and KeyboardEvent on the same function

[databell]

Do I add it like this?

stage.addEventListener(KeyboardEvent.KEY_DOWN, slideRight);
stage.addEventListener(KeyboardEvent.KEY_DOWN, slideLeft);

I've been reading through a bunch of different tutorials to figure out how to do this and this is the closest I've found although I'm still confused as to how to target the left and right arrow keys to enable the functions.
