Im using this script to TimeStamp in a comment all fields. The workbook is becoming a mess now:function onEdit(e){  // Set a comment on the edited cell to indicate when it was changed.  var range = e.range;  range.setNote('Last modified: ' + new Date());}What I would like is to have a script that only timestamps in comment for just the column K in all sheets on my workbook. Please help? Alternatively, and even better, can the timestamp be shown in Column N instead?
