Notes

The article User Interface Event Handlers contains a list of event handler names.
Be aware though, that the preceding "on" in the listed names must be eliminated when used with the ctrlSetEventHandler command. e.g. instead of _control ctrlSetEventHandler ["OnLBSelChanged", ""]; // WRONG use _control ctrlSetEventHandler ["LBSelChanged", ""]; // RIGHT
