Agreed: we should move towards a more orthogonal/composable design,
where the granularity of the operation (char, word, line, sexp,
paragraph, page, defun, ...) and the operation itself (move, mark) and
the direction and all independent such that we can use any combination
of them.

Both at the ELisp level and at the key-binding level.
