In GNU Emacs, try running M-: (dot) RET.

I think this alias was an aid to porting Lisp from some other Emacs variant in the 80s that used "dot" instead of "point". Never figured out which. It isn't mg because mg doesn't run Lisp.

Emacs called it “point” which is not as far. The cursor is just the visible widget.
