GUITexture KeyInput

Hey, I want a GUI Texture to enable and disable when I press the B Key. Is this possible?

Try this

var guiTexture : Texture2D;    // The GUI texture to use
private var z : int;
private var guiTrue : boolean;

function Update () {

if (Input.GetKeyDown ("b")){
    z = (z % 2) + 1;
    if(z == 1){
    guiTrue=true;
        }else{
        guiTrue=false;
        print(z + " False");
        }
    }
}

function OnGUI()
{
        if(guiTrue){
        GUI.DrawTexture(Rect(0, 0, Screen.width, Screen.height), guiTexture);
        print(z + " True");
    }
}
