e17 enlightenment desktop uses Sh-Alt-R and Ctl-Alt-R to change workspaces

Enlightenment uses two separate keystroke combinations to change workspaces.
Sh-Alt-rightarrow
Ctl-Alt-rightarrow

It should only use one. And that should be Ctl-Alt-right(or left) arrow.
Reason. Sh-Alt-arrow is in use constantly in other programs, particularly EMACS org-mode, to promote and demote headings.

Alternately, if there is a way to easily disable an enlightenment desktop shortcut, this should be made clearer.
