The macro screen context

Within a single macro screen, the macro runtime performs the actions in the order in which they occur in the <actions> element. This is the same order in which you haved ordered the actions in the Action listbox.

You are not required to create any actions for a macro screen. If there is no <actions> element or if the <actions> element is empty, then the macro runtime goes straight to the next section of macro screen processing, which is selecting the next macro screen to be processed.
