Answer 1

Another approach (no plugin needed) it to just use ctrlKey property of the event object that gets passed in. It indicates if Ctrl was pressed at the time of the event, like this:

$(document).keypress("c",function(e) {
  if(e.ctrlKey)
    alert("Ctrl+C was pressed!!");
});

See also jquery: keypress, ctrl+c (or some combo like that).
