Can't find the GREP list codes reference

Well, it sould be there :

http://help.adobe.com/en_US/InDesign/6.0/WS1952D538-1335-4b1d-BA5E-FA5 A176FDC9Fa.html

But it seems it's not here anymore. (I found the link there : http://indesignsecrets.com/grep)

After a little while browsing/searching Adobe and livedocs pages, I'm unable to find this particular ressource.

Does someone can help me find it (or a copy of it...) ?
