How to get the "ctrl c" or mouse copy event in a Powerpoint 2013 Addin (developed in C#)?

Question

Code below is not trapping character type in MS Powerpoint, It does just outside of Powerpoint and how can I catch the "control copy" or "right mouse click copy" inside this code?

Use a custom ribbon.

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
  <commands>
    <command idMso="Cut" onAction="CopyIntercept" />
    <command idMso="Copy" onAction="CopyIntercept" />
  </commands>
</customUI>

public void CopyIntercept(IRibbonControl control, ref bool CancelDefault)
{
}

You might be able to do this with a Ribbon Designer, but the sample above is for an XML ribbon.
