Hi all,

Recently made the transition from flash/as2 to flex/as3 have to say I’m loving it! Thought i’d experiment a bit and test the water making a simple live chat application already run into my first snag.

```auto
private function keyPressed(e:KeyboardEvent):void
        {
            switch(e.keyCode)
            {
                case 13:
                    sendText();
                break;
            }
        }
private function sendText():void
        {
            if(inputText.text == "")
            {
                trace("text field is blank");
            }else{
                textDisplay.appendText(inputText.text + "
");
                inputText.text = "";
                stage.focus = inputText;
            }
        }

```

This is called using:

```auto
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed);

```

The problem I’m experiencing is when you first hit enter and add the text to the display box is registers the enter and adds it aswell.

```auto
textDisplay.appendText(inputText.text + "
");

```

This is the main offender. I’m just wondering how I would find the last character and ignore everything else after that? Kind of similar to the php explode.

Heres a picture to better demonstrate:
