4.3.2 Do element
The do element can be expressed in two ways: in card wide scope (like 'Enter' in Example 3-7) or in
deckwide scope as in the template (like 'Ask Help', 'Contact' and 'Back' in Example 3-7). Do elements
will be stored in the browser’s options list together with the preloaded options (Figure 4-13).
