Action is a higher level abstraction that at the event handler level. For instance, I have things like NewInvoiceAction, DeleteInvoiceAction, ProvideFeedbackAction, etc. They each register themselves as event listeners on the app and maintain an internal state -- thus allowing them to perform their action at any time without needing to know how they were triggered. They also maintain their own enabled/disabled state in a similar fashion. Then I wire up my buttons, menus, and keystrokes to my actions, and my get auto-disabling of those buttons and menu items for free.
