1.1 mike 873:
874: <p>The user agent may also provide access to its default context
875: menu, if any, with the context menu shown. For example, it could
876: merge the menu items from the two menus together, or provide the
877: page's context menu as a submenu of the default menu.</p>

879: <p>If the user dismisses the menu without making a selection,

1.1 mike 884:
885: <p>Context menus must not, while being shown, reflect changes in the

887: until dismissed.</p>
1.1 mike 888:
889: <p>User agents may provide means for bypassing the context menu
890: processing model, ensuring that the user can always access the UA's
891: default context menus. For example, the user agent could handle
892: right-clicks that have the Shift key depressed in such a way that it
893: does not fire the <code title="event-contextmenu">contextmenu</code>
894: event and instead always shows the default context menu.</p>
