is an option for Cell that gives a list of actions to perform when specified events occur in connection with a cell in a notebook.
  • CellEventActions->{"event1":>action1, "event2":>action2, ...} specifies that actioni should be evaluated whenever "eventi" occurs in connection with a cell.
  • The possible event specifications are the same as for EventHandler.
  • Settings for CellEventActions are often defined at the level of stylesheets, rather than for individual cells or notebooks.
  • By default, any action specified for an event by CellEventActions will override any default action that Mathematica would take for that event.
