I have to hold down control with the pinky, and reach b and f with
two fingers that are in quite different bends and directions.  Three
fingers being bent out of their rest position and in need of pressing
coordinated make for RSI.

I will still need to use my pinky for it.

We are not talking Ctrl-A, and besides, little and ring finger share
the same sheath for their sinews.  Since you have to move them
independently, (CTRL down A down A up CTRL up), you have to let them
work against each other.

No vi user with a modicum of experience will use cursor keys instead
of hjkl-Navigation.

Right.  For the same of beginners, mostly.  Experienced vi users will
use hjkl, whereas most experiences Emacs users will escape to using
cursor keys when available.

vi movement commands on the main keyboard are single-key, not
control-combinations.  And they are all located on different fingers
of a single hand in rest position (shifted to the left by 1 key in
contrast to the 10-finger typist rest position, the only slight
