Shortcut works just like an internal link - it can put in the navigation 
  as a fake page. The problem of shortcut is that ACT and CUR don't work 
with them. In my mind this is a bug. Even if shortcut is just an 
internal link it should behave like a normal page in the navigation.

"Show content from this page instead" works like a normal page - if you 
want to use the same content in different branches use advanced page and
use "Show content from this page instead". CUR and ACT work ok in this case.

BTW. I have made for links SHORTCUT and EXTURL as new link behaviors.
Works with Typo3 3.7.0.
The original menu file has SPC and USR, which are not actual link 
states. In my mind it is consitent to add also SHORTCUT and EXTURL
to class.tslib_menu.php.
