Editing a trigger is just as easy as adding a trigger. You can either double-click on the trigger in the Triggers panel or select the trigger and click on the Edit icon. In both instances, the Trigger Wizard will appear. You can make your changes and click on OK to close the Trigger Wizard.
Alternatively, if a trigger is visible in the Triggers panel with blue underlined text, you can edit that trigger by clicking on the blue underlined text and selecting another option. In the next screenshot in the Exercise 1 section, you will see that Button 1 and Button 2 are in blue underlined text. In this example, when you click on the text, the other available layers will appear for selection (for example, Button 1, Button 2, Button 3, and Button 4).
