// AppKit will call -[NSUserInterfaceValidations validateUserInterfaceItem:] to
// validate UI items. Any item whose target is FirstResponder, or nil, will
// traverse the responder chain looking for a responder that implements the
// item's selector. The top menu (configured in MainMenu.xib) can contain menu
// items with selectors that are implemented by Chromium's
// RenderWidgetHostViewCocoa or NativeWidgetMacNSWindow classes. These classes
// live in the Cocoa view hierarchy and will be triggered only if the browser
// window is focused. When the browser window is not focused these selectors
// will be forwarded (by Chromium's CommandDispatcher class) to `[NSApp
// delegate]` (this class). The particular selectors of interest here are
// |-commandDispatch:| and |-commandDispatchUsingKeyModifiers:| which will have
// a tag value from include/cef_command_ids.h. For example, 37000 is IDC_FIND
// and can be triggered via the "Find..." menu item or the Cmd+g keyboard
// shortcut:
//
// <menuItem title="Find..." tag="37000" keyEquivalent="g" id="209">
// <connections>
// <action selector="commandDispatch:" target="-1" id="241"/>
// </connections>
// </menuItem>
//
// If |-validateUserInterfaceItem:| returns YES then the menu item will be
// enabled and execution will trigger the associated selector.
//
// This implementation is based on Chromium's AppController class.
