How to know which control was clicked when sharing an action?

I'm implementing actions (in a TActionManager) for a user interface. Some controls, when clicked, execute the same action. However, in that action handler, I need to know which control was actually clicked by the user. But the Sender is a TAction instead of the originating control.

How can I identify which control using this action was actually pressed by the user?

You can obtain this information from the ActionComponent property of the action.
