// The background process (e.g. '/background.js'). 

if (opera.contexts.menu) {
  var menu = opera.contexts.menu;
  // Create a menu item properties object
  var itemProps = {
    contexts: ['editable'],
    title: 'Mail autofill',
    id: '[email protected]'

  // Create a menu item with the specified properties
  var item = menu.createItem(itemProps);
  // Add the menu item to the context menu
// An injected script (e.g. '/includes/injected.js').

  // Insert the menu item's ID into the target element
  opera.contexts.menu.onclick = function(menuEvent) {
    menuEvent.srcElement.value = menuEvent.target.id;
