Capture the "cut" event

Hi!

I cannot find any information on how to capture and handle the "cut" event before (or while) it occurs... I would greatly appreciate any information on this...

I can capture the "paste" event like this, but it does not work for "cut":
ThisEditor.on('paste',function(event)
{
if (<user can make changes> == false) {
event.stop();
event.cancel();
}
})

Note that I don't mean pressing the "CTRL-X" or "SHIFT-DELETE" keys here; those actions I can capture and handle. What I can't capture and handle is when a user highlight's text in a ckEditor, right-click's on the ckEditor, and clicks "Cut" in the popup window.

Thanks in advance for your help!
