Go to Page action will switch the page to the one you specified, the content in current page will be hidden and those on the target page will then be displayed.
You can specify the target page index (starts with 1), or select the target page from the page list.
Once this action get performed, the HTML5 simulation goes to the target page, which means all content in the previous page will be hidden, and the content in target page will be displayed. Please notice this action will not trigger the Element Hidden event, instead the "Page Loaded" event will be triggered at the target page. If the target page has master page, the Loaded as Master Page event will also be triggered on the master page too.
