How can I “undo” the programmatic insertion of text into a textarea?

Question

I have a textarea and a button. Clicking the button causes text to be inserted into the textarea.

Is there a way to allow a user to press Ctrl/Cmd+z to undo the inse

Answer 1

$("#target").keypress(function(event) {
  if ( event.which == 'Z' && first press == 'Cmd' && second press == 'Ctrl') {//check for key press
     event.preventDefault();
    text.value = defaultValueForTextField
   }
});

That should be what you are looking for. First and Second press will need to be saved as you want combo presses. You will indeed need to save a default text value though.
