Thank you Chris, your reply was helpful. I didn't know that I can use the free form name of the group in the kickstart. However, to be clear about my original question:
If you install the "Administration Tools" group, the resultant kickstart file (anaconda-ks.cfg) will have a shortened entry of "@admin-tools" not "@Administration Tools". That's the associations I was looking for. For example, what is the shortened version of "@Graphical Internet"? Now that I can draw upon your wisdom, I really don't care, I guess.
Thank you for your help.
