How can I detect a keypress in blockly and see which key it was?

[Zubair Quraishi]

I wish to detect when the enter key is pressed in blockly so that I can trigger a code evaluation, but I can't figure out how to detect key presses in Blockly. I see the event code such as the following:

function onFirstComment(event) {
  if (event.type == Blockly.Events.CHANGE &&
      event.element == 'comment' &&
      !event.oldValue && event.newValue) {
    alert('Congratulations on creating your first comment!')
    workspace.removeChangeListener(onFirstComment);
  }
}
workspace.addChangeListener(onFirstComment);

but the Blockly.Events.XXX only allows the following values:

One of Blockly.Events.CREATE, Blockly.Events.DELETE, Blockly.Events.CHANGE, Blockly.Events.MOVE, Blockly.Events.UI

Is there any way to drill in to one of these events and find out which key was pressed?

just a quick update on this. i know I did not receive any replies on this thread but I have been informed that it is not possible to find out which key was pressed, not without modifying the blockly code itself. As a workaround I make a guess as to when enter is pressed by saying that if no key is pressed for 1 second then enter has probably been pressed.
