title: Undo and redo features in a Tkinter Text widget?
body: <p>I need to make both a <kbd>Control</kbd> + <kbd>Z</kbd> and <kbd>Shift</kbd> + <kbd>Control</kbd> + <kbd>Z</kbd> function in a Tkinter <code>Text</code> widget, so that one may undo and redo things. </p>
  
  <p>Does anyone have an idea on how to do it?</p>
