There are \circlearrowleft and right which are slightly different.
I added keyboard shortcuts '@ < tab' and '@ > tab' (revision 13088).

But since the characters you want exist in Unicode (U+27F2 and U+27F3),
it suffices to select a font that supports them.

I just gave the usual backslash the semantics of a division
in math mode (revision 13089).

I recall that you may do this your self using
Insert -> Semantics -> Division.
