Once you create a hypertext link in a Text object you can edit the list of actions that you have added to it.
Select the Text box that contains the hypertext link that you want to edit.
Click inside the word or phrase that forms the hypertext you want to edit until the I-beam cursor appears in that word or phrase.
Right-click to open the right-click menu, and then select the Edit Hypertext option. This will open the Actions dialog for the hypertext text action.
Make your changes to the actions as you want.
Click on the Apply button to save your changes.
