Flash using arrow keys to move between frames in an animation

Question

Hi,
Im currently creating a calculator on flash and I would like to be able to move to the next part of the calculator (the next frame) by using the arrow keys on my keyboard
This is my current code to move between the frames using a buttons.
stop();
var input1:String;
var input2:String;
var Res:Number;
var Quote:Number;
txtLen.restrict = "0-9"
txtWid.restrict = "0-9"
BtnCon2.addEventListener(MouseEvent.CLICK,fnCall)
function fnCall(Event:MouseEvent):void{
  input1 = txtLen.text;
  input2 = txtWid.text;
  Res = parseInt(input1) * parseInt(input2);
  Res.toString();
  gotoAndPlay(21)
  txtArea.text = String(Res);
BtnRes1.addEventListener(MouseEvent.CLICK,fnRes1)
function fnRes1(Event:MouseEvent):void{
  gotoAndPlay(1);
Im trying to do the same thing that im doing with my buttons but with my arrow keys
Thanks

Another way to write what Ned said is instead of multiple if's, you could do something like:
switch(yourEvent.keyCode) {
     case Keyboard.RIGHT:
          fnCall(null);
          break;
     case Keyboard.LEFT:
          fnRes1(null);
          break;
     case Keyboard.UP:
          //do up stuff
          break;
     case Keyboard.DOWN:
          //do down stuff
          break;
     default:
          trace('I\'m confused by this key.');
          break;
Some people find this syntax more legible.
