# Document Event-Driven Macros

This section describes how to assign scripts to application, document or form events.

You can automatically execute a macro when a specified software event occurs by assigning the desired macro to the event. The following table provides an overview of document events and at what point an assigned macro is executed.

Event | An assigned macro is executed... | routine
--- | --- | ---
Start Application | ...after a LibreOffice application is started. | OnStartApp
Close Application | ...before a LibreOffice application is terminated. | OnCloseApp

Most events relate to documents, except OnStartApp, OnCloseApp, OnCreate and OnLoadFinished that occur at application level. OnSubComponentOpened, and OnSubComponentClosed events are fired by database's forms.

Writer documents are triggering those specific events: OnLayoutFinished, OnMailMerge, OnMailMergeFinished, OnFieldMerge, OnFieldMergeFinished and OnPageCountChanged.
