Control E Fill Down Functionality Removed in R8.3

I apologize if this has been asked/ansewred a million times already but not having much luck with the seartch functions of the forum.

I recently  purchased and installed P6 R8.3.0 (build 6424) and I still have fill down capability, but only by right clicking and selecting from the menu. In previous versions that I am more familiar with, this was available as a short cut using CTRL-E. But not in this newer version.

Comments greatly appreciated.
