Well, I actually meant the help fullness of the command itself and
that users are already used to M-r.  It would be interesting to know
when this key combination was introduced.

True, that's a point.

Not necessarily at all circumstances.  Some more commands could be as
intelligent/subservient as C-x zzzzzz (just repeating the last char
for repetition) C-x ^ or C-x comes to mind.

Admitted, I'm not using M-r as often as C-s or M-f for example but in
the process of positioning the cursor as near as possible to a visual
target within the window (my use of M-r) one is impatient and happy to
use short key sequences or might otherwise succumb to the mouse.
