Appliction.LoadLevel +=1?

Hey guys,

Is there a way i can make a script load the next level instead of making a new script for each level?

so for example, instead of duplicting the script and adding one to the number, can i do something like this;

Application.LoadLevel(+=1);

Thanks,

Application.LoadLevel( Application.loadedLevel + 1 );

this dosent just load the next level but you dont need a seporate script for each level

function Update () {
	if (Input.GetKey ("1"))
		Application.LoadLevel ("1");
	if (Input.GetKey ("2"))
		Application.LoadLevel ("2");
		if (Input.GetKey ("3"))
		Application.LoadLevel ("3");
		if (Input.GetKey ("m"))
		Application.LoadLevel ("menu");
}
