Hi Chris,
I have tried the example and: 1) When you click on the JTextArea, then it takes the focus. 2) Therefore all key events from that moment are going to the JTextArea (not to the scene). 3) When you press Ctrl+Tab, then the focus is moved to the next JComponent which is the scene view. 4) Then you can use Delete key again.
Solution: Into the KeySelectProvider.select method, add following line: scene.getView ().requestFocus (); Also I would recommend you to add an action to the scene itself. The new action would be calling the "requestFocus" method too.
Regards, David

Hi David!
Well this exhibits the same behavior....when I select another widget it won't delete....
