Removing "Birth" from the Facts menu in Family Tree Maker 2 for Mac

I'm running FTM for Mac 2, version 21.2.5.487. A lot of the trees on Ancestry have--IN ERROR--christening dates entered as birth dates. I want to create a tree that, correctly, ONLY has christening dates. Thus, from the "Customize View" menu, I need to delete "Birth" altogether. Alas, both Birth and Death are sitting under the "Selected individual facts." Can someone give me the keystrokes to DELETE "Birth" from those facts? This is really important, because the incorrect trees are already proliferating on Ancestry.com.
