[TYPO3-english] conditional menu based on menu page-id

[David Banning]

I would like one item on a menu to display differently according to it's 
page id, but I can't seem to find the matching syntax for the menu/page id.

For instance

[globalVar = TSFE:id=799]
   libmenu.1.IFSUB.doNotLinkIt = 1
[END]

will match when you are -on- page 799, but I want the menu link
that -points- to page 799 to change, regardless of where you are on the site.
