The purpose of page2 commands is to show usage of option button list  
and cascading menu. 
 
If a cascading menu (also called named group) only contains dimmed 
/invisible commands, the command itself that holds the cascading menu will also 
be made dimmed/invisible by the framework.  
 
Whether dimming or visibility is used will be determined by the  
phone style (pen style dimm commands while softkey style makes them  
invisible). Applications can stick to use SetAvailable() which will  
encapsulate the difference between different phone styles. 
 
If you dimm a cascading menu command, all commands in that named group will be 
auto-dimmed. You only have to undim the cascading menu command to have the  
group members auto-undimmed. The same functionality also exists in softkey  
style user interfaces, but in softkey style the framework auto-hide/unhide  
instead of dimm.
