Selectors are jQuery-style selectors
based on the content of the page to be demonstrated. If you are familiar with how the page is constructed, feel free to
enter selectors specific to the page being demonstrated. The default selector is the body tag which
means the entire page gets signed including menus, navigation and even the iSigner player window.
If you don't know what any of this means, leave "Selectors" blank and the demo will use a reasonable default value.
