I believe these started as the emacs (and later readline) keybindings.

I imagine they work in R under a terminal because of inclusion of the
readline library, not because "they work with everything".

Alternatively, you could use the ESS package with emacs or xemacs
under OS X (but I can understand if emacs doesn't seem very
Macintosh-like :-). Anyone who has attended presentations by both Steve
Jobs and Richard Stallman would have difficulty imagining the two of
them finding common ground.
