On the Event Handlers form, use field to determine the order in which custom event handlers execute for a given event, in cases where event handlers already exist for that event.

On the Event Handler Sequence form, this field is display-only.

If you have a handler selected in the Keep With field, you must also select an option in this field. If no handler is selected in the Keep With field, this field is optional.

You can use these two drop-down lists to modify the default handler sequence order. For more information and examples, see "About Event Handling and Order" in the Guide to the Application Event System.

This list displays a variable number of options, depending on whether or not you have a handler selected in the Keep With field. This table lists and describes the possible options:

Option	Description/Availability
(Blank)	If you select something in the Keep With field, you cannot leave this field blank.
First	This option causes your handler to execute first, before any others.
Before	This option causes your handler to execute before the handler selected in the Keep With field.
Instead	This option causes your handler to execute instead of the handler selected in the Keep With field. When this option is selected, the handler selected in the Keep With field does not execute at all. For possible exceptions to this rule, see "Overriding Others' Handlers" in the Guide to the Application Event System.
Exclusively Instead	This option is similar to the Instead option. The difference is that, if this option is selected, it overrides all other handlers, even those that use the Instead option with the same handler. For more information about this option, see "Overriding Others' Handlers" in the Guide to the Application Event System.
After	This option causes your handler to execute after the handler selected in the Keep With field.
Last	This option causes your handler to execute last, after all other handlers have finished.
