An action is a set of keystrokes that is sent to the host. You can define actions to be taken from a host screen. Actions are used for the following purposes:
To navigate if the next screen is not recognized.
To create an alternate path to take you to another screen if you do not want to use one of the recorded paths.
To re-display the same screen without setting a path. This is useful if you are scrolling through a multiple-page screen, or are using the same data entry screen repeatedly.
