Hello,

You should use the predefined constants defined here: [http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyEvent.html](http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyEvent.html)

For example, catching the enter key:`from java.awt.event import KeyEvent
if event.keyCode == KeyEvent.VK_ENTER:
	print "yep"`Best,

Based on your code, I want to print “yep” when I press the “Enter” Key on a Text Field.  
I wrote this code on the PropertyChange Event Script of this Text Field component.  
I used the following code, per your recommendation **but it gives me an error** :

```auto
import KeyEvent
if event.keyCode == KeyEvent.VK_ENTER: 
   print "yep"

```

You are probably already aware but just in case… print is for the script editor etc not a client

Put this in a key pressed event in your component:

```auto
if event.keyCode == event.VK_ENTER:
	system.gui.messageBox("Test")

```
