IDE Key Mapping Nightmare!

IDE Key Mapping Nightmare!  I use Ctrl + Home or Ctrl + End fairly frequently to go to the beginning/end of a file.  But these key sequences were clobbered by a 3rd Party tool.  No amount of research has found a way for me to restore these key maps. Hey I've loaded Castalia, Bookmarks, GExperts, CnPack & DDevExtension.  Any way to fix this in the XE7 IDE?
