You can set up actions for pages or for objects on a page. All of the actions are displayed in the Actions Organiser for the page or object.
Each action is made up of two parts:
The Trigger – this is the event that starts the action or list of actions.
The Action – this is the action that will happen when the trigger is activated.
Open the Actions dialog box for the page or object you want to add an action to:
For pages, double-click the right mouse button on a blank area of the page currently open in the Creator Editor window.
For objects, double-click the right mouse button on the object to which you want to add the actions.
Click on the Trigger tab to show the Trigger menus from which you can select a trigger.
Click on one of the Trigger Menus to display the triggers available in each category.
Click and hold down the left mouse button over your selected trigger and drag to the Actions organiser on the left side of the Actions dialog box. This will add the trigger to the Actions organiser.
Select a Mouse Click Modifier if you want from the Mouse Click tab.
Note:
This tab will only appear when you select a Mouse trigger as your trigger. Other triggers may also display an additional tab – see Choosing a Trigger for more information.
Click on the Actions tab to add an action to your trigger, and then click on one of Action menus to display the actions available in each category.
Click and hold down the left mouse button over your selected action and drag to the Actions Organiser on the left side of the Actions dialog box over the trigger you have just added. This will add the action to the trigger.
Click on the QuickAnim tab to add an complex animation actions to your trigger, and then click on one of animation categories to display the actions available in each category.
Note:
Actions added via this system will take 1 second by default. You can easily edit the inserted actions to change the timing.
Each action has its own specific settings that you can modify. A fourth level tab will appear after the Programming tab in the Actions dialog box that allows you to set particular options for that action. For example, choosing the Show action will allow you to specifically set which objects on the page to show.
You can add as many triggers to the Action Organiser as you want. Also, you can have as many actions under a trigger as you want.
The splitter button 
between the Actions Organiser and the tabs on the right of the Actions dialog allows you to expand the amount of space taken up by the Organiser. Move the mouse anywhere above the splitter button and the splitters vertical line will turn blue and the cursor will change to the 
shape. Click and drag the vertical bar left and right to resize the panels while the cursor is displayed.
